Multiple choice

The idea that the major portion of Earth would be submerged followed by a prolonged ice age as a result of global warming is implausible. Weather forecasters cannot dependably predict the next day’s weather. Yet the effects of the global warming on our planet’s structure and climate would follow the same physical laws that govern normal changes in the weather being predicted. If scientists cannot predict the day-to-day weather using our current knowledge, they certainly cannot predict the effects of global warming on Earth’s climate.

Which of the following statements would most seriously weaken the author’s conclusion?

  1. The theory predicting the effects on Earth being submerged by water causing return of ice age is based on studies that are readily available to weather forecasters.

  2. The effects of Earth being submerged will create drastic atmospheric changes rather than the type of day-to-day weather changes seen.

  3. Weather forecasters do not require predictions to be 100 percent accurate.

  4. Attempts to predict the effects of natural catastrophes such as global warming have been found to be less reliable than normal weather predictions.

  5. None of these

B Correct answer
Explanation

This answer shows that the inability to predict daily weather changes doesn’t indicate an inability to predict weather changes that would result from submergence of Earth as a result of global warming.
