I'd be happy to help you with the exercises. 42. The correct answer is A. The man opened the window in order to get some fresh air in the room. This sentence combines the two original sentences by using a subordinate clause "in order to get some fresh air in the room" to indicate the purpose of the man's action. 43. The correct answer is A. Mr. Smith, to whom I spoke on the phone last night, is very interested in our plan. This sentence combines the two original sentences by using a non-essential clause "to whom I spoke on the phone last night" to provide additional information about Mr. Smith. 44. The correct answer is D. Although Mike graduated with a good degree, he joined the ranks of the unemployed. This sentence combines the two original sentences by using a contrasting conjunction "although" to indicate that Mike's graduation with a good degree did not lead to employment. 45. The correct answer is C. No matter how hard she tried, she could hardly pass the driving test. This sentence combines the two original sentences by using a subordinate clause "no matter how hard she tried" to indicate the effort she put into passing the test, and the main clause "she could hardly pass the driving test" to indicate the outcome. Now, let's move on to the passage-based questions: 46. The correct answer is B. Man acts as if he does not belong to nature. The sentence "Man, however much he may like to pretend the contrary, is part of nature" suggests that humans tend to think they are separate from nature, but in reality, they are a part of it. 47. The correct answer is D. Concerned. The author's tone throughout the passage is one of concern and warning about the dangers of pesticides and their impact on the environment and human health. 48. The correct answer is A. is not the worst of the negative consequences resulting from use of pesticides. The author suggests that the sudden death caused by exposure to large amounts of pesticides is not the major problem, but rather the delayed effects of absorbing small amounts of pesticides over time. 49. The correct answer is C. the danger does not become apparent immediately. The author suggests that people tend to ignore the delayed effects of exposure to chemicals because the danger is not immediately apparent, making it easy to overlook. 50. The correct answer is A. people find invisible diseases difficult to deal with. Dr. Dubos' remarks suggest that people are more impressed by diseases with obvious signs, implying that they tend to overlook or find it difficult to deal with diseases that have no obvious signs or symptoms.
