A few states in this country are considering legislation that would prohibit schools from using calculators before the sixth grade. Other states take a different position. Some states are insisting on the purchase of graphing calculators for every student in middle school. This paragraph best supports the statement that
A.
there are at least two opinions about the use of calculators in schools.
B.
calculators are frequently a detriment to learning math.
C.
state legislators are more involved in education than ever before.
D.
the price of graphing calculators is less when schools buy in bulk.
The paragraph clearly states that there are two differing opinions with regard to the use of calculators in the classroom. Although some people may believe that choice b is true, the paragraph does not indicate this. Choice c has no relation to the paragraph. Choice d makes logical sense, but the paragraph says nothing about cost. Choice e is an opinion that is not given in the paragraph.
Human technology developed from the first stone tools about two and a half million years ago. At the beginning, the rate of development was slow. Hundreds of thousands of years passed without much change. Today, new technologies are reported daily on television and in newspapers. This paragraph best supports the statement that
A.
stone tools were not really technology.
B.
stone tools were in use for two and a half million years
C.
there is no way to know when stone tools first came into use.
D.
In today's world, new technologies are constantly being developed
The last sentence states that new technologies are reported daily, and this implies that new technologies are being constantly developed. There is no support for choice a.With regard to choice b, stone tools were first used two and a half million years ago, but they were not neessarily in use all that time. Choice c is clearly wrong since the paragraph states when stone tools first came into use. Although some may agree that choice e is true, the author of the paragraph does not give support for this opinion.
Today's workforce has a new set of social values. Ten years ago, a manager who was offered a promotion in a distant city would not have questioned the move. Today, a manager in that same situation might choose family happiness instead of career advancement. This paragraph best supports the statement that
A.
most managers are not loyal to the corporations for which they work.
B.
businesses today do not understand their employees needs.
C.
employees social values have changed over the past ten years.
D.
career advancement is not important to today's business managers.
A change in employee social values over the past ten years is implied in the whole paragraph, but particularly in the first sentence. Choice a is incorrect because the loyalty of the managers to their corporations is never discussed. There is no support for choice b. In choice d, perhaps career advancement is less important than it once was, but the paragraph does not indicate that advancement is unimportant to managers. Choice e is an opinion that is not supported.
Yoga has become a very popular type of exercise, but it may not be for everyone. Before you sign yourself up for a yoga class, you need to examine what it is you want from your fitness routine. If you're looking for a high-energy, fast-paced aerobic workout, a yoga class might not be your best choice. This paragraph best supports the statement that
A.
yoga is more popular than high-impact aerobics.
B.
before embarking on a new exercise regimen, you should think about your needs and desires.
C.
yoga is changing the world of fitness in major ways
The second sentence points out that people should examine what they want from a fitness routine before signing up for a new exercise class. There is no evidence to support choice a. Choice c might sound reasonable due to the fact that the paragraph tells us that yoga has become very popular, but this statement is not supported by the information provided in the paragraph. Choices d and e are also not supported since the paragraph doesn't tell us whether yoga is good for both body and mind or what people think about it.
It is well known that the world urgently needs adequate distribution of food, so that everyone gets enough. Adequate distribution of medicine is just as urgent. Medical expertise and medical supplies need to be redistributed throughout the world so that people in emerging nations will have proper medical care. This paragraph best supports the statement that
A.
the majority of the people in the world have never been seen by a doctor.
B.
food production in emerging nations has slowed during the past several years.
C.
most of the world's doctors are selfish about giving time and money to the poor.
D.
many people who live in emerging nations are not receiving proper medical care
This answer is implied by the statement that redistribution is needed so that people in emerging nations can have proper medical care. Choices a, b, and c are not mentioned in the passage. Choice d is also incorrectΓÇöthe passage indicates that the distribution of medicine, not its production, is inadequate.
There are no effective boundaries when it comes to pollutants. Studies have shown that toxic insecticides that have been banned in many countries are riding the wind from countries where they remain legal. Compounds such as DDT and toxaphene have been found in remote places like the Yukon and other Arctic regions. This paragraph best supports the statement that
A.
toxic insecticides such as DDT have not been banned throughout the world.
B.
more pollutants find their way into polar climates than they do into warmer areas
C.
studies have proven that many countries have ignored their own antipollution laws.
D.
DDT and toxaphene are the two most toxic insecticides in the world.
The support for this choice is in the second sentence, which states that in some countries, toxic insecticides are still legal. Choice b is incorrect because even though polar regions are mentioned in the paragraph, there is no support for the idea that warmer regions are not just as affected. There is no support for choice c. Choice d can be ruled out because there is nothing to indicate that DDT and toxaphene are the most toxic. Choice e is illogical.
