000 NEARBY SUN-LIKE STARS, AND IMMEDIATELY TEST CANDIDATE SIGNALS TO...

1,000 nearby Sun-like stars, and immediately test candidate signals to see if they are Project Phoenix in

origin. It is important that Project Phoenix continue to operate, because radio interference from Earth

sources is growing, and may soon interfere with our ability to detect possible extraterrestrial signals. In

order to overcome this growing interference, ever better antenna systems are being developed

Question 44: What does the passage mainly discussed?

A. possible explanations for radio signals of unknown origin

B. the origin of life on other planets

C. the life stories of scientists involved in SETI

D. efforts to search for signals from extraterrestrial civilizations

D. a description of several other failed attempts to pick extraterrestrial radio signals

Question 46: “Verified” in bold in paragraph 3 is closest in meaning to

A. received B. underlined C. checked D. discovered

Question 47: It can be inferred from the passage that a major limitation of earlier searches for alien radio

signals was

A. the limited number of signals that might be extraterrestial

B. the slowness of the verification process

C. the lack of scientific interest in this topic

D. the difficulty of obtaining government funding

Question 48: Which of the following would NOT distinguish Project Phoenix from previous SETI

experiments?

A. It can only search in a few directions B. It uses the world’s largest antennas

C. It immediately tests candidate signals D. It is comprehensive

Question 49: “Scrutinize” in bold in the last paragraph is closest meaning to

A. process B. establish C. examine D. orbit

Question 50: Where is this passage most likely seen in?

A. a book of short stories. B. a personal website

C. a popular science journal D. an editorial in a local newspaper
