Bank depositors in the United States are all financially protected against bank failure because the government insures all individuals bank deposits．An economist argues that this insurance is partly responsible for the high rate of bank failures，since it removes from depositors any financial incentive to find out whether the bank that holds their money is secure against failure．If depositors were more selective，then banks would need to be secure in order to compete for depositors money．

45．The economist's argument makes which of the following assumptions?
(A) Bank failures are caused when big borrowers default on loan repayments．
(B) A significant proportion of depositors maintain accounts at several different banks．
(C) The more a depositor has to deposit，the more careful he or she tends to be in selecting a bank.
(D) The difference in the interest rates paid to depositors by different banks is not a significant factor in bank failures．
(E) Potential depositors are able to determine which banks are secure against failure．


46．Which of the following，if true，most seriously weakens the economist's argument?
(A) Before the government started to insure depositors against bank failure，there was a lower rate of bank failure than there is now．
(B) When the government did not insure deposits，frequent bank failures occurred as a result of depositors fears of losing money in bank failures．
(C) Surveys show that a significant proportion of depositors are aware that their deposits are insured by the government．
(D) There is an upper limit on the amount of an individual's deposit that the government will insure，but very few individuals deposits exceed this limit．
(E) The security of a bank against failure depends on the percentage of its assets that are loaned out and also on how much risk its loans involve．

Laws requiring the use of headlights during daylight hours can prevent automobile collisions. However, since daylight visibility is worse in countries farther from the equator, any such laws would obviously be more effective in preventing collisions in those countries．In fact，the only countries that actually have such laws are farther from the equator than is the continental United States.
Which of the following conclusions could be most properly drawn from the information given above?
(A) Drivers in the continental United States who used their headlights during the day would be just as likely to become involved in a collision as would drivers who did not use their headlights．
(B) In many countries that are farther from the equator than is the continental United States poor daylight visibility is the single most important factor in automobile collisions-
(C) The proportion of automobile collisions that occur in the daytime is greater in the continental United States than in the countries that have daytime headlight laws．
(D) Fewer automobile collisions probably occur each year in countries that have daytime headlight laws than occur within the continental United States．
(E) Daytime headlight laws would probably do less to prevent automobile collisions in the continental United States than they do in the countries that have the laws．

@bloodformoney : Hi friend i thought that option A was the answer for 6.1, but OA provided by you is D. Could you elaborate pls?

Let us Have a look at this again :

6.1 Commentator: The theory of trade retaliation states that countries closed out of any of another countrys markets should close some of their own markets to the other country in order to pressure the other country to reopen its markets. If every country acted according to this theory, no country would trade with any other
The commentators argument relies on which of the following assumptions?
(A) No country actually acts according to the theory of trade retaliation.
(B) No country should block any of its markets to foreign trade.
(C) Trade disputes should be settled by international tribunal.
(D) For any two countries, at least one has some market closed to the other
(E) Countries close their markets to foreigners to protect domestic producers.

Since,the commentator is talking about the theory of retaliation

Options E and C are absurd as they talk out of context
B) could have been a conclusion but not assumption
Options A and D are close
But D is more appropriate since we are more concerned about how countries act with respect to the theory

Transnational cooperation among corporations is experiencing a modest renaissance among United States firms，even though projects undertaken by two or more corporations under a collaborative agreement are less profitable than projects undertaken by a single corporation．The advantage of transnational cooperation is that such joint international projects may allow United States firms to win foreign contracts that they would not otherwise be able to win．
2．Which of the following statements by a United States corporate officer best fits the situation of United States firms as described in the passage above?
(A) ＂We would rather make only a share of the profit and also risk only a share of a possible loss than run the full risk of a loss．＂
(B) ＂We would rather make a share of a relatively modest profit than end up making none of a potentially much bigger profit．＂
(C) ＂We would rather cooperate and build good will than poison the business climate by all-out competition．＂
(D) ＂We would rather have foreign corporations join us in American projects than join them in projects in their home countries.＂
(E) ＂We would rather win a contract with a truly competitive bid of our own than get involved in less profitable collaborative agreements.＂

3．Which of the following is information provided by the passage above?
(A) Transnational cooperation involves projects too big for a single corporation to handle．
(B) Transnational cooperation results in a pooling of resources leading to high-quality performance．
(C) Transnational cooperation has in the past been both more common and less common than it is now among United States firms．

Monthly employee evaluations are an excellent tool for managers. With them, employees that are not productive can be removed from the company, and efficient workers rewarded, and all within the space of a month.

The argument above logically depends on which of the following assumptions?

A Workers do not in turn complete evaluations of the management of the company.
B Unproductive employees often refuse to co-operate with the managers doing the evaluations, because they see these evaluations as a violation of their privacy.
C Most studies indicate that employee evaluations have no bearing whatsoever on worker satisfaction.
D Evaluations can identify with some accuracy whether an employee is productive or not.
E Employee evaluations are a better source of information about employee grievances than are monthly staff meetings.

SET 9:

A CEO of a major company has noted a serious decline in worker productivity within the last 3 years. According to a report completed by a consultant, productivity dropped by 35% during that time. The CEO has therefore intiated a plan to boost productivity in which employees receive stock options in the company.

Which of the following, if true, would make the CEO's plan logically sound?

A Studies indicate that owning part of something makes one work harder to make it successful.
B Workers respond more to increases in salary than to the threat of being fired or demoted.
C The drop in worker productivity is due to the management policies of the current CEO and the Board of Directors.
D The financial situation of the company is actually more grave than the issue of employee productivity.
E The outside consultant hired to study the productivity of the company is often very accurate in her work.

My Take

(2) The wolf had been tagged and released by the biologists only three miles away from a sheep ranch that provided a large, stable population of prey animals.

set-5

Biologists attached a radio transmitter to one of a number of wolves that had been released earlier in the White River Wilderness Area as part of a relocation project. The biologists hoped to use this wolf to track the movements of the whole pack. Wolves usually range over a wide area in search of prey, and frequently follow the migrations of their prey animals. The biologists were surprised to find that this particular wolf never moved more than five miles away from the location in which it was first tagged. Which one of the following, if true, would by itself most help to explain the behavior of the wolf tagged by the biologists?

(1) The area in which the wolves were released was rocky and mountainous, in contrast to the flat, heavily- wooded area from which they were taken.
(2) The wolf had been tagged and released by the biologists only three miles away from a sheep ranch that provided a large, stable population of prey animals.
(3) The White River Wilderness Area had supported a population of wolves in past years, but they had been hunted to extinction.
(4) Although the wolves in the White River Wilderness Area were under government protection, their numbers had been sharply reduced, within a few years of their release, by illegal hunting.
