Hello all

I took GMAT and got 620 what screwed me on the test, is that a hard tricky question came up, nd since i'm stuborn by nature i kept wasting time on it, and in the end i started guessing to complete on time, i probably guessed like 4 or 5 questions, but since that day im working almost everyday in this website im practicing on 700 level questions by topic, but problem is there's too many of them, i probably worked more than 400 + questions, my job is very demanding i cannot keep up, what do you think guys? also i'm planning to buy some CAT, so i'm open to your opinions :|

The daguerreotype, the earliest medium of photography that now exists

The daguerreotype, the earliest medium of photography that now exists only as a novelty for collectors and hobbyists, is created using photochemical processes that capture images formed on metal plates coated with bitumen. Even though bitumen is among the cheapest available materials in the market, a recent survey of hobbyists who create daguerreotypes in the twenty-first century revealed that the process is far more expensive than that of digital photography.

Which of the following, if true, most helps to explain the above finding?

A) The cost of bitumen has not increased significantly since the time in which the daguerreotype was first invented.
B) Digital photography in the twenty-first century involves the use of costly SLR cameras that use multiple lenses, many of which are actually more expensive than the camera itself.
C) Many hobbyists are also collectors who are willing to purchase expensive equipment in order to preserve what they consider a dying art form.
D) The process to coat photographic plates to prepare them to capture images can only be carried out at specialized laboratories that charge extra rates for services that are not frequently in demand.
E) Some hobbyists use materials other than bitumen to coat the metal plates on which the image is captured.

During the Civil War, railroads were the quickest way to transport

During the Civil War, railroads were the quickest way to transport troops across locations. However, the railroads were originally used to transport agricultural products, particularly wheat, from their place of production to their place of sale. Clearly, the militarization of the railroads must have affected the transport of agricultural goods during the war, thereby also impacting the sales of such products. So, sales of wheat during the Civil War must have been considerably lower than sales of wheat before the war.

Which of the following is an assumption made by the author?

A) Sales of wheat after the war were greater than sales of wheat during the war.
B) The amount of wheat produced in the country during the war was less than the amount produced before the war.
C) The railroads were set up for the purpose of transporting agricultural goods.
D) Before the war, a significant amount of the wheat that was sold was transported via the railroads
E) Wheat that could not be sold could not be utilized in any other way.

Experia Inc., a pioneer in online retailing in the cosmetics business

Experia Inc., a pioneer in online retailing in the cosmetics business, sells all its products only through its website. While evaluating its various marketing channels, the company discovered that it attracts two times as many visitors for every dollar spent on Google than on Cosmetico, an online magazine. The company also found that the average purchase of a customer does not depend on whether the customer came through Google or the magazine. The company has, therefore, decided to shift some of its marketing funds from the magazine to Google to increase its overall profits.

Which of the following most strongly undermines the ability of the companys plan to increase its profits?

A) An average reader of a Cosmetico magazine has income that is several times greater than the income of an average Google user.
B) The conversion ratio from visitors to customers is several times higher in case of Cosmetico than in the case of Google.
C) Last time, when the company shifted more of its resources from Cosmetico to Google, it resulted in an immediate increase in its sales.
D) Given the large presence of Google across various geographies, the visitors that come from Google are much more spread geographically than those who come from Cosmetico.
E) By investing time and money on writing articles in Cosmetico, Experia can reduce its customer acquisition costs to half to what they are now.

The Environment Protection Agency (EPA) is rigorously working on eradicating the Hemlock Woolly Adelgid (HWA) fungi that has damaged hemlock trees on the east coast of the country. In addition to other steps to eradicate the fungi, the EPA has conducted awareness sessions for hemlock growers on the extent of damage that HWA can cause and given the growers detailed instructions on how to identify and destroy the fungi.

Which of the following, if true, would provide the most support for the prediction that the EPAs action will have its intended effect?

A) Some fungal infestations on pine trees closely resemble the HWA fungi.
B) Reports have shown that the HWA also affects another plant species known as the bleeding hearts, a species that is commercially cultivated by hemlock growers in the same area as hemlocks.
C) The eradication of HWA is likely to cause a serious imbalance in the ecosystem of the east coast area.
D) Hemlock trees have also been considerably damaged by the fungus E. Coli, which is native to the east coast area and attacks trees through their roots.
E) Some sub-species of hemlock trees can resist fungal infestations without human intervention.

The gun lobby’s attempt to stop doctors from warning about the severe

The gun lobbys attempt to stop doctors from warning about the severe risks posed by guns in homes is outrageous and unconstitutional. Children aged 5 to 14 years in the United States are 11 times more likely to be killed accidentally with a gun than similarly aged children in other developed countries are. Moreover, more than 40 percent of gun-owning households with children store their guns unlocked, and one quarter of these homes store them loaded.

The considerations given best serve as part of the argument that

A) children must be provided proper counseling in schools on the dangers associated with the use of guns.
B) the United States must learn from other developed countries on reducing the murder rate.
C) doctors must be allowed to give patients frank advice about the risks posed by guns in the home.
D) the gun lobby should be allowed to express its views.
E) children aged 5 to 14 years must be provided special protection to protect them from gun related crimes.

Which of the following statements most explains the paradox in the above argument?

A) OldFort United has not been playing more matches this year.
B) Football critics are often wrong in their predictions.
C) OldFort Uniteds decision to hire Wayne Bruce has turned out well for the team as he is the leading scorer for the team this year.
D) Many critics have raised questions about the actual nationality of James McGuel, making it likely that he will be excluded from the World Championship squad for the country.

In an attempt to improve the economic and social welfare of the people, the government has recently announced a scheme under which it will provide certain staple foods at 30% discount to the authorized dealers. The reduction in the prices of these foods will significantly improve the economic conditions of the people from low income groups.

Which of the following would be most useful to establish in evaluating the argument?

A) Whether discounting the prices of staple foods is the only way to improve the economic and social welfare of the people
B) Whether people with medium or high income groups will also benefit from the scheme
C) Whether the expenditure on staple foods under question forms a significant chunk of the income of people from low income groups
D) Whether the people from low-income groups will appreciate some other kind of financial assistance more than the one being offered by the government
E) Whether this scheme would have an adverse impact on the budgetary allocation of other welfare initiatives taken by the government.

An independent study comparing dispute resolution by the police forces in two countries, one in which the police officers are always armed and others in which police officers do not usually carry any fire-arms, found that the armed police force shot significantly more suspects than the unarmed one. The findings of the study clearly show that regular possession of a fire arm prompts police officers to disregard the use of less harmful alternatives such as tasers, CS spray etc.

Which of the following, if true, most strengthens the above argument?

A) The unarmed police officers often undergo training programs related with sensitizing them towards people in general.
B) In the cases considered, the overall level of danger involved to the unarmed police officers was relatively lower than the overall level of danger involved in cases in which the armed police officers used their fire-arms.
C) In most of the cases studied, the use of the fire-arms was not initiated by the suspects being chased by the armed police.
D) In many countries, the police officers work in teams of two and more often than not, one of the officers always carries a fire-arm.
E) Studies show that in countries where the police forces are armed, the rate of death penalty is higher than in countries in which the police forces are unarmed

Declines in amphibian populations - pretty interesting RC from OG16

Declines in amphibian populations

There are recent reports of apparently drastic declines in amphibian populations and of extinctions of a number of the world's endangered amphibian species. These declines, if real, may be signs of a general trend toward extinction, and many environmentalists have claimed that immediate environmental action is necessary to remedy this "amphibian crisis", which, in their view, is an indicator of general and catastrophic environmental degradation due to human activity.

To evaluate these claims, it is useful to make a preliminary distinction that is far too often ignored. A declining population should not be confused with an endangered one. An endangered population is always rare, almost always small, and, by definition, under constant threat of extinction even without a proximate cause in human activities. Its disappearance, however unfortunate, should come as no great surprise. Moreover, chance events - which may indicate nothing about the direction of trends in population size - may lead to its extinction. The probability of extinction due to such random factors depends on the population size and is independent of the prevailing direction of change in that size.

For biologists, population declines are potentially more worrisome than extinctions. Persistent declines, especially in large populations, indicate a changed ecological context. Even here, distinctions must again be made among declines that are only apparent (in the sense that they are part of habitual cycles or of normal fluctuations), declines that take a population to some lower but still acceptable level, and those that threaten extinction (e.g., by taking the number of individuals below the minimum viable population). Anecdotal reports of population decreases cannot distinguish among these possibilities, and some amphibian populations have shown strong fluctuations in the past.

It is Indisputably true that there is simply not enough long-term scientific data on amphibian populations to enable researches to identify real declines in amphibian populations. Many fairly common amphibian species declared all but extinct after severe declines in the 1950s and 1960s have subsequently recovered, and so might the apparently declining populations that have generated the current appearance of an amphibian crisis. Unfortunately, long-term data will not soon be forthcoming, and postponing environmental action while we wait for it may doom species and whole ecosystems to extinction.

The high rate of depression among people in countries that do not receive much sunlight most of the year prompted researchers at the University of Frankphyl to study the link between a lack of vitamin D, which is found naturally in sunlight, and the incidence of depression. The study found that in patients with a relatively severe degree of depression, the level of vitamin D was lower than in patients with a milder degree of depression. The researchers hence concluded that people in such countries can avert depression by including vitamin D supplements in their diet.

Which of the following is required for the conclusion drawn by the researchers to hold true?

A) There is a significant difference in the effect that vitamin D obtained directly from sunlight and that obtained from dietary supplements has on the health of a patient suffering from depression.
B) Patients with the most severe degree of depression belonged to countries that do not receive sunlight up to extended periods of six months.
C) Both people with a severe degree of depression and those with a mild degree of depression belonged to the same economic strata.
D) The lack of vitamin D is not triggered by depression in patients.
E) The required dose for vitamin D supplements is significantly higher for patients with severe depression than for patients with mild depression.

The state of Orifiozis has been trying to increase the planting of trees in its prime cities. One of the reasons that residents hesitate to grow trees is the price of water. In order to increase the planting of trees in these cities, an environmental organization has suggested that the state reduce the water taxes on homes that have more than four trees that are older than three years.

Which of the following, if true, most threatens the plans prospects for success?

A) Some residents are certain that the implementation of this suggestion will help.
B) While water costs is the number one concern for most of the residents of Orifiozis, some residents have other minor concerns as well, such as the time required to maintain the trees.
C) Most homes in the prime cities have space only for a maximum of two trees to grow.
D) Some trees grow to full length in less than three years.
E) Water taxes in Orifiozis are not as high as those in the neighboring state, which is known for its extensive greenery.

So I gave my GMAT yesterday and got a score of 760. But my Quantitative is very low. Its 48 (73 percentile). My verbals 47. Which I think pushed my score high. I am absolutely shocked. Well I did have to guess the last few questions. But even then the score is bad.
I need some advise here. I am planning to apply to the top five B schools. But I have heard they have a 80 percentile cutoff for Quantitative. I wanna know how strict they are about that. Does anyone have any idea? I mean I do understand that there are a lot of factors, but my questions is..is a low on Quantitative a strict no-no?
I am confused about retaking the test. What do you think about that. This was my second attempt and I had scored 710 (Q 49, V 38) two months ago.
I am really confused and any help will really be appreciated.
