114. In the closing days of the civil War, President Abraham Lincoln was
planning to graciously welcome the defeated confederate states back into the
Union. After Lincoln was assassinated, however, the "Radical Republicans" in
Congress imposed martial law in the South, creating resentment that caused
problems well into this century. Had Lincoln lived, the history of regional
conflict in 20th century America would have been considerably different.
All of the following assumptions underline the argument above EXCEPT The
imposition of martial law in the South was primarily responsible for the
resentment felt in the South Had he lived, lincoln would have treated hte
defeated South as he had planned Lincoln would have been able to prevent the
Radical Republicans in Congress from imposing martial law in the South Factors
other than the imposition of martial law in the South affected the history of
regional conflicts in 20th century America
115 A politician wrote the following: "I realize there are shortcomings to the
questionaire method. However, since I send a copy of the quetionnaire to every
home in the district, I believe the results are quite representative.... I think
the numbers received are so large that it is quite accurate even though the
survey is not done scientifically" Most people who received the questionnaire
have replied Most people in the district live in homes. the questionnaire method
of data collection is unscientific A large, absolute number of replies is
synonymous with accuracy
116 A worldwide ban on the production of certain ozone-destroying chemicals
would provide only an illusion of protection. Quantities of such chemicals,
already produced, exist as coolants in millions of refrigerators. When they
reach the ozone layer in the atmosphere, their action cannot be halted. So there
is no way to prevent these chemicals from damaging the ozone layer further.
Which of the following, if true, most seriously weakens the argument above?
It is impossible to measure with accuracy the quantity of ozone-destroying
chemicals that exist as coolants in refrigerators.
In modern societies, refrigeration of food is necessary to prevent unhealthy and
potentially life-threatening conditions.
Even if people should give up the use of refrigerators, the coolants already in
existing refrigerators are a threat to atmospheric ozone.
The coolants in refrigerators can be fully recovered at the end of the useful
life of the refrigerators and reused.

characters. All gamblers are attracted by pool halls.
