280. (a) At the Threshold of Neutrino Astronomy (Because the first para says that "the detection of cosmic neutrinos could provide new information about a wide variety of cosmic phenomena and about the history of the universe" and the last line says "Neutrino astronomy will doubtless bring its own share of surprises" so the focus here is on Neutrino Astronomy
281. (c) Neutrino astronomy can be expected to lead to major breakthroughs in astronomy (Because in the last paragraph the author describes the discoveries of radio galaxies, quasars and pulsars as surprises and says that "Neutrino astronomy will doubtless bring its own share of surprises" i.e, it is going to bring major breakthroughs in neutrino Astronomy)
282. (a) suggest that the potential findings of neutrino astronomy can be seen as part of a series of astronomical successes (Because "The extension of astronomy from visible light to radio waves to x-rays and gamma" tells about the progress of astronomical successes and the neutrino Astronomy is the latest.
283. (d) carry information about their history with them (Because the first para tels that "Furthermore, neutrinos carry with them information about the site and circumstances of their production" and "therefore, the detection of cosmic neutrinos could provide new information about a wide variety of cosmic phenomena and about the history of the universe")
284. (c) detect the presence of cosmic neutrinos (Because the second para tells that "No apparatus can detect neutrinos unless it is extremely massive, because great mass is synonymous with huge numbers of nucleons (neutrons and protons), and the more massive the detector, the greater the probability of one of its nucleon’s reacting with a neutrino")
285. (a) rare (Because the first para states that "the neutrino interacts with other particles so rarely that a neutrino can cross the entire universe")
286. (c) The infrequency of their interaction with other matter (Because the first para tells about the rare interaction of neutrinos with other particles and mentions that "Neutrinos can thus escape from regions of space where light and other kinds of electromagnetic radiation are blocked by matter")
287. (d) charged particles and light (Because the third para tells that "when a neutrino interacts with a particle in an atom of seawater, the result is a cascade of electrically charged particles and a flash of light that can be detected by the sensors")
288. (c) observation of neutrinos that were artificially created (Because the second para states that "since then virtually all research with neutrinos has been with neutrinos created artificially in large particle accelerators")
