Early data on seat-belt use showed that seat-belt wearers were less likely to be killed in road accidents. Hence, it was initially believed that wearing a seat-belt increased survival chances in an accident. But what the early analysts had failed to see was that cautious drivers were more likely to wear the belts and were also less likely to cause 'big accidents', while reckless drivers were more likely to be involved in 'big' accidents and were less likely to wear the belts.
Which of the following, if true, could an opponent of the view presented above best cite as a reason for recommending continued use of seat-belts?
  • a)
    Careful drivers who are involved in accidents caused by reckless drivers, would be more likely to survive if wearing a belt
  • b)
    All drivers should be required by law to wear a belt
  • c)
    The ratio of 'big' to 'small' road accidents is very small
  • d)
    In fatal accidents seat-belt wearers in the front seat are less likely to survive than those wearing seat belts in the back seat
  • e)
    On average, careful drivers pay lower insurance premiums than do drivers who have been involved in accidents.
Correct answer is option 'A'. Can you explain this answer?

The argument suggests that seat belt use might not increase the chances of survival, and so the best way to oppose the argument would be to find cases where seat-belt use does increase survival. Hence A is the best answer.

Justification for recommending continued use of seat-belts:

Careful drivers involved in accidents caused by reckless drivers:
- Careful drivers who are involved in accidents caused by reckless drivers may have a higher chance of survival if they are wearing a seat belt.
- Seat belts can provide protection in situations where the driver is not at fault but is still involved in a collision caused by others.
Therefore, even though the initial analysis may have overlooked the correlation between seat-belt use and driver behavior, there are still valid reasons to recommend the continued use of seat belts, especially in scenarios where cautious drivers may be involved in accidents caused by reckless drivers.

Similar GMAT Doubts

Experts anticipate that global atmospheric concentrations of carbon dioxide (CO2) will have doubled by the end of the twenty-first century. It is known that CO2 can contribute to global warming by (5) trapping solar energy that is being reradiated as heat from the Earth’s surface. However, some research has suggested that elevated CO2 levels could enhance the photosynthetic rates of plants, resulting in a lush world of agricultural abundance, and that this CO2 (10) fertilization effect might eventually decrease the rate of global warming. The increased vegetation in such an environment could be counted on to draw more CO2 from the atmosphere. The level of CO2 would thus increase at a lower rate than many experts have (15) predicted.However, while a number of recent studies confirm that plant growth would be generally enhanced in an atmosphere rich in CO2, they also suggest that increased CO2 would differentially increase the growth (20) rate of different species of plants, which could eventually result in decreased agricultural yields. Certain important crops such as corn and sugarcane that currently have higher photosynthetic efficiencies than other plants may lose that edge in an atmosphere (25) rich in CO2. Patterson and Flint have shown that these important crops may experience yield reductions because of the increased performance of certain weeds. Such differences in growth rates between plant species could also alter ecosystem stability. Studies have (30) shown that within rangeland regions, for example, a weedy grass grows much better with plentiful CO2 than do three other grasses. Because this weedy grass predisposes land to burning, its potential increase may lead to greater numbers of and more severe wildfires in (35) future rangeland communities.It is clear that the CO2 fertilization effect does not guarantee the lush world of agricultural abundance that once seemed likely, but what about the potential for the increased uptake of CO2 to decrease the rate of global (40) warming? Some studies suggest that the changes accompanying global warming will not improve the ability of terrestrial ecosystems to absorb CO2. Billings’ simulation of global warming conditions in wet tundra grasslands showed that the level of CO2 (45) actually increased. Plant growth did increase under these conditions because of warmer temperatures and increased CO2 levels. But as the permafrost melted, more peat (accumulated dead plant material) began to decompose. This process in turn liberated more CO2 to (50) the atmosphere. Billings estimated that if summer temperatures rose four degrees Celsius, the tundra would liberate 50 percent more CO2 than it does currently. In a warmer world, increased plant growth, which could absorb CO2 from the atmosphere, would (55) not compensate for this rapid increase in decomposition rates. This observation is particularly important because high-latitude habitats such as the tundra are expected to experience the greatest temperature increase.Which one of the following best describes the function of the last paragraph of the passage?
