Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which person learned more about the size of the ozone hole over Antarctica? Ben and Harry were studying about the climatic history of Earth. Ben was more attracted to learning about early Ice Ages, while Harry was curious about the Earth atmosphere and read about ozone depletion and its consequences. Hint: Beginning in the late 1970's, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels.

Problem: Given the question: Please answer correctly the following question related to the paragraph below. Would scientist A increased our understanding of the world more or less than scientist B? This year scientist found concrete evidence of existence of black holes by taking photograph of one. Unfortunately, the originator of black hole theory, Stephen Hawking, was never awarded a Nobel prize despite letting science advance in big leap because his theory could not be verified during his lifetime. On the other hand, scientist B has received Nobel prize because he has based his theory on the earlier theory of scientist A. Hint: The above example shows how science generally advances. New evidence is usually used to improve earlier ideas rather than entirely replace them. In this way, scientists gradually refine their ideas and increase our understanding of the world. On the other hand, sometimes science advances in big leaps. This has happened when a scientist came up with a completely new way of looking at things. For example, Albert Einstein came up with a new view of gravity. He said it was really just a dent in the fabric of space and time.

Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which friend didn't start avoiding carcinogens? Two friends found out more about cancer. Bill got scared and started making healthy lifestyle choices, while Dan carried on with his life as if nothing happened.
