Logical Reasoning MCQ Set 24

Question 1: Authorities concerned with mass transport in metropolitan cities are struggling with deficits. Commuters complain about delays and breakdowns, cuts in service, and fares higher than they are accustomed to paying. For all these reasons and because the price of fuel is still not prohibitive, the number of commuters using public transportation has fallen, adding to the deficits.
Which among the following statements about the relationship between the number of commuters using public transportation and the price of fuel is best supported by the above passage?

1. With the rise in the price of fuel, there is a rise in the number of commuters using public transportation.
2. Even if the price of fuel rises, the number of commuters using public transportation will continue to decline.
3. The number of commuters using public transportation will rise, if the price of fuel rises to a prohibitive level.
4. Most of the commuters using public transportation do not use fuel, therefore fluctuations in the price of fuel is unlikely to affect the number of commuters using public transportation.
5. The price of fuel is always low enough to make private transportation cheaper than public transportation; therefore fluctuations in the price of fuel is unlikely to affect the number of commuters using public transportation.

Question 1: Pharmaceutical firms are now engaged in the production of analogues of endorphins, peptides, which are thought to transmit messages among brain cells, which bring about pain relief. The pharmaceutical firms claim that the analogues, when injected into the bloodstream, will lead to effective and long-lasting pain relief by increasing the action of peptides already present in the brain.
The claims put forth by the pharmaceutical firms would be considerably weakened if it were true that

1. Compared to the other types of neurotransmitters present in the brain, endorphins remain active for a longer time period.
2. Certain peptides have been traced in parts besides the brain, like the alimentary canal and the skin.
3. It is easier and cheaper to produce analogues of peptides in the laboratory than the peptides themselves.
4. Analogues of peptides, which are found naturally in the body are often filtered from the blood before the blood circulates in the brain.
5. Endorphins interact chemically both with other naturally occurring peptides and with the brain's other neurotransmitters.

Among the following statements which would most damage the above argument if proved to be true?

1. There was no attempt made in the survey to ascertain whether the surveyed teachers had any previous exposure to microcomputers.
2. Teachers interested in microcomputer technology were more likely to complete and return the questionnaires than others.
3. Irrespective of their subject area, their expertise and their teaching experience questionnaires were received by the teachers.
4. After the survey results were tabulated there have been many developments in the applications of microcomputer technology.
5. A company manufacturing and selling microcomputers conducted the survey.
