    Q.18-19.
    Half of the subjects in an experiment--- the experimental group --- consumed large quantities of a popular artificial sweetner. Afterwards, this group showed lower cognitive abilities than did the other half of the subjects--- the control group--- who did not consume the sweetner. The detrimental effects were attributed to an amino acid that is one of the sweetner’s principal components.
Q18 Which of the following, if true, would best support the conclusion that some ingredient of the sweetner was responsible for the experimental results?
(1) The Quality of sweetner consumed by the individuals in the experimental group is considered safe by medical uthorities
(2) The amino acid referred to in the conclusion is a component of all proteins, some of which must be consumed for adequate nutrition.
(3)

Most consumers of the sweetner do not consume as such of as the experimental group members did.
(4) The two groups of subjects were evenly matched with regard to cognitive abilities prior to the experiments.
Q19 Which of the following, if true, would best help explain how the sweetner might produce the observed effects?
(1) A high level of amino acid in the blood inhibits the synthesis of a substance required for normal brain functioning.
(2) Because of the sweetner being used primarily as a food additive, adverse reactions to it are rarely noticed by consumers.
(3)

Subjects in the experiments did not know whether they were consuming the sweetner or a harmless substance.
(4) The amino acid that is a constituent of the sweetener is also sold separately as a dietary supplement.
Q20 Editorial.

Regulations recently imposed by the Government of Katanga call for unprecedental reduction in the amounts of pollutants, manufactures are allowed to discharge into environment.  It will take costly new pollution control equipment requiring expensive maintenance to comply with these regulations.  Resultant price increases.

For Katangan manufactured goods will lead to the loss of some export markets.  Clearly, therefore, annual exports of Katangan manufactured goods will in future occur at diminishing levels.
Q20

Which of the following, if true, most seriously WEAKENS the arguments in the editorial?
(1) By international standards, the Levels of pollutants currently emitted by some of Katanga’s manufacturing plants are not considered excessive.
(2) Savings form utilizing the chemicals captured by the pollution control equipment will remain far below the cost of maintaining the equipment.
(3) The proposed regulations include a schedule of fines for non-compliance that escalate steeply in cases of repeated non-compliance
(4) The need to comply with the new regulations will stimulate the development within Katanga of new pollution control equipment for which a strong worldwide demand is likely to emerge.
Q21

Automobile Dealer’s Advertisement
The Highway Traffic Safety Institute reports that the XL1000 has the fewest injuries per accident of any car in its class. This shows that the XL1000 is one of the safest cars available today.
Q21

Which of the following, if true, most seriously WEAKENS the argument in the advertisement?
(1) The Highway Traffic Safety Institute issues reports only once in a year.
(2) The difference between the number of injuries per accident for XL1000 and that of other cars in its class is Quite pronounced
(3) In recent years many more XL1000s have been sold than have any other kind of cars in its class.
(4) Cars in the class to which the XL1000 belongs are more likely to be involved in accidents than are other types of cars.
Q22

Choloroflurocarbons (CFCs) pose known dangers to public health. Only when the United States government imposes a specific ban on the industrial use of CFCs cost – effective and thus reduce public health hazards.
Q22 Which of the following is an assumption on which the assertion made above is based?
(1) The alternative to CFCs currently available are not widely used because they are not familiar to sufficient number of industry scientists.
(2) The alternatives to CFCs are less hazardous to public health than are CFCs.
(3) The use of CFCs can result in employment time lost because of illness.
(4) CFCs are currently the most serious public health hazard engendered by the industry in the United States.
Q23 The large amount of Carbon Dioxide (CO2) now being released into the atmosphere burning fossil fuel will not, in fact, result in green house effects-------- an increase in average global temperatures. Since plants use CO2 in large quantities if the supply is increased, they are able to grow larger and multiply more rigorously, and atmospheric CO2 concentrations will eventually become stable.
Q23 Which of the following, if true, would most seriously WEAKENS the conclusion that a green house effect will not result from current release of large amounts of CO2 into the atmosphere?
(1) When plant decays, they produce methane, another gas that can have a marked green house effect.
(2) The expected rise in average global temperatures, has not yet been observed
(3) Since the beginning of the Industrial Revolution (1790) increased atmospheric concentrations of CO2 have resulted in agricultural productivity.
(4) Ocean waters absorb CO2 at a greater rate when the atmospheric concentration of CO2 is higher.
