2a: Logical Reasoning

Directions to Solve Read the paragraph carefully and determine the main point the author is trying to make. What conclusion can be drawn from the argument? Each paragraph is followed by five statements. One statement supports the author's argument better than the others do.

1. One of the warmest winters on record has put consumers in the mood to spend money. Spending is likely to be the strongest in thirteen years. During the month of February, sales of existing single-family homes hit an annual record rate of 4.75 million. This paragraph best supports the statement that

consumer spending will be higher thirteen years from now than it is today.
warm winter weather is likely to affect the rate of home sales.
during the winter months, the prices of single-family homes are the lowest.
more people buy houses in the month of February than in any other month.

2. In the past, consumers would rarely walk into an ice cream store and order low-fat ice cream. But that isn't the case today. An increasing health consciousness combined with a much bigger selection of tasty low-fat foods in all categories has made low-fat ice cream a very profitable item for ice cream store owners. This paragraph best supports the statement that

low-fat ice cream is more popular than other kinds of ice cream.
low-fat ice cream produces more revenue than other low-fat foods.
ice cream store owners no longer think that low-fat ice cream is an unpopular item.
ice cream store owners would be better off carrying only low-fat ice cream.

3. 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

before embarking on a new exercise regimen, you should think about your needs and desires.
yoga benefits your body and mind
most people think that yoga isn't a rigorous form of exercise.
yoga is more popular than high-impact aerobics.
yoga is changing the world of fitness in major ways

4. During the last six years, the number of practicing physicians has increased by about 20%. During the same time period, the number of healthcare managers has increased by more than 600%. These percentages mean that many doctors have lost the authority to make their own schedules, determine the fees that they charge, and decide on prescribed treatments. This paragraph best supports the statement that doctors

resent the interference of healthcare managers.
are less independent than they used to be.
no longer have adequate training.
are making a lot less money than they used to make
care a great deal about their patients.

Read the below passage carefully and answer the questions 5-7:

Giving children computers in grade school is a waste of money and teachers time. These children are too young to learn how to use computers effectively and need to spend time on learning the basics, like arithmetic and reading. After all, a baby has to crawl before she can walk.

examples of high school students who use computers improperly
evidence that using computers makes learning to read difficult
proof that the cost of computers is coming down
research on the effect of computer games on children
studies showing computers are expensive

6. Which of the following, if true, would weaken the speaker's argument?

a demonstration that computers can be used to teach reading and arithmetic
analysis of the cost-effectiveness of new computers versus repairing old computers
recent grade reports of students in the computer classes
a visit to a classroom where computers are being used
examples of adults who do not know how to use computers

7. Which of the following methods of argument is used in the previous passage?

displaying statistics that back up the speaker's point
relying on an analogy to prove the speaker's point
attacking the beliefs of those who disagree with the speaker
comparing different methods of learning
a specific example that illustrates the speaker's point
