Option D is correct - It gives the reason which may result in increase in the use of bamboo in the construction industry. Option A is incorrect because it is a general statement and does not explains why the scientists are expecting the sudden increase in use of bamboo as construction material. Option B is incorrect because if true it is a weakener and out of scope. Option C is incorrect because it is irrelevant to the prediction. Option E is again a weakener.

Q1. A proposal for a new building fire safety code requires that fireretardant insulation no longer be sprayed on steel girders in the factory, but be sprayed on once the girders have arrived at the building site. This will eliminate the dislodging of the insulation in transit and reduce fatalities in catastrophic fires by an estimated 20%. Which of the following, if true, represents the strongest challenge to the new proposal? (A) The fire-retardant insulation will also be required to be one inch thicker than in the past. (B) Studies have shown that most dislodgement of insulation occurs after the girders arrive on site. (C) Catastrophic fires represent only 4% of the fires reported nationally. (D) The proposed safety code will add considerably to the cost of new construction. (E) In most of Europe, spraying fire-retardant insulation onto steel girders at the building site has been required for the past ten years.

Q2. Although studies have found bamboo to be a better raw material than cement and mortar for use in the construction industry, as it is cheaper and more environment-friendly, most builders are concerned that home buyers will be resistant to the idea of houses built of bamboo. Nevertheless, experts predict that the use of bamboo in the construction industry will soon see a rapid increase. Which of the following, if true, most strongly supports the prediction outlined above? A. Although it grows only in specific regions, bamboo is relatively easy to grow and does not require as much maintenance as other crops. B. Bamboo cannot be grown in coastal areas since salt water and humidity have been proven to have an adverse effect on the growth of the plant in such areas. C. Many building materials sourced from natural resources can also be used to make items such as household furniture and farming implements. D. According to recent studies, bamboo is much more resilient than it was previously believed to be, and houses made out of bamboo are expected to require much less maintenance than those made of more commonly used materials. E. Environmental organizations have recently become much more vocal about the multiple ways in which the environment is being exploited.
CR Questions April- 12 :Q1. Cultural anthropologists have hypothesized that smiling is a submissive gesture that signals lower social status.
In a recent study, researchers examined photographs in 200 newspapers and magazines and found that people with more wealth and influence were less likely to smile for photographs. Based on the results of this study, an advertising agency concluded that advertisements for high-end products targeting wealthy and influential people would be more effective if those advertisements used unsmiling models to convey higher social status and exclusivity.
The conclusion of the advertising agency is based on which of the following assumptions?
(A) Most people would be more attracted to a product if it makes them look more wealthy or influential than they actually are.
(B) Models who do not smile in photographs are generally wealthier and more influential than models who smile in photographs.
(C) Many advertisements for high-end products depict models engaging in activities that usually cause people of average wealth and influence to smile.
(D) Most wealthy and influential people view a person who smiles in a photograph as less wealthy and influential than themselves.
(E) In general, wealthy and influential people are attracted to products and images that convey higher social status and exclusivity.
Q2. Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage. Unfortunately,
the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones. Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer. However,
since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, the use of genetically engineered seeds of this kind is likely to become widespread.
In the argument given, the two portions in boldface play which of the following roles?
(A) The first supplies a context for the argument; the second is the argument’s main conclusion.
(B) The first introduces a development that the argument predicts will have a certain outcome; the second is a state of affairs that the argument denies will be part of that outcome.
(C) The first presents a development that the argument predicts will have a certain outcome; the second acknowledges a consideration that weighs against that prediction.
(D) The first provides evidence to support a prediction that the argument seeks to defend; the second is that prediction.
(E) The first and the second each provide evidence to support the argument’s main conclusion.
