39. Which scientist would be likely to disagree with the idea that life on planets other than Earth could have different biochemistries? A. Scientist 1 B. Scientist 2 C. Both scientists D. Neither scientist 40. Which of the following questions would be –Š‡ ‘•– †‹ˆϐ‹…—Ž– ˆ‘”…‹‡–‹•– ͳ –‘ †‡ˆ‡† his theory against? F. Why was there more meteorite activity earlier in Earth’s history? G. Why have other meteors not brought other life based on a different biochemistry? H. Why did complex life emerge suddenly? J. Why should meteor activity have any connection to the origin of life? Passage VII A seismographic station can detect how far away an earthquake occurred, but it cannot determine the direction of the earthquake. Any given station can therefore report that the epicenter of an earthquake occurred somewhere on the circumference of a circle a certain distance around the station with the seismograph in its center. The map below shows the data recorded for an earthquake at three different seismic stations (A, B, and C). Intersections of the three seismic stations’ curves are marked by roman numerals.

Could Scientist 2 believe that life exists on other planets without affecting his hypothesis? A. Yes, as long as he believes that life elsewhere has a different biochemistry. B. Yes, because wherever the chemicals required for life exist, life can begin. C. No, because then he has to admit that meteorites brought life from these planets. D. No, because then he has to admit that meteorites that came from pieces of similar planets brought life to Earth.

42. Which station was closest to the earthquake epicenter? F. A G. B H. C J. Cannot be determined from the given information 43. Given the information from stations A and B only, which site(s) is (are) possible for the earthquake epicenter? A. I only B. III only C. II and III only D. I and III only 44. Given the information from stations A and C only, which site(s) is (are) possible for the earthquake epicenter? F. I only G. III only H. II and III only J. I and III only
