Virtually everything astronomers known about objects
outside the solar system is based on the detection of photons-quanta of electromagnetic radiation. Yet there is another form of radiation that permeates the universe: (5) neutrinos. With (as its name implies) no electric charge, and negligible mass, the neutrino interacts with other particles so rarely that a neutrino can cross the entire universe, even traversing substantial aggregations of matter, without being absorbed or even dlected. Neu- (10)trinos can thus escape from regions of space where light and other kinds of electromagnetic radiationare blocked by matter. Furthermore, neutrinos carry with them information about the site and circumstances of their production: therore, the detection of cosmic neutrinos (15)could provide new information about a wide variety of cosmic phenomena and about the history of the uni- verse. But how can scientists detect a particle that interacts so infrequently with other matter? Twenty-five years (20)passed between Pauli’s hypothesis that the neutrino existed and its actual detection: since then virtually all research with neutrinos has been with neutrinos created artificially in large particle accelerators and studied under neutrino microscopes. But a neutrino telescope, (25) capable of detecting cosmic neutrinos, is difficult to co- nstruct. 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 pro- (30) bability of one of its nucleon’s reacting with a neutrino. In addition, the apparatus must be sufficiently shielded from the interfering fects of other particles. Fortunately, a group of astrophysicists has proposed a means of detecting cosmic neutrinos by harnessing the (35) mass of the ocean. Named DUMAND, for Deep Under- water Muon and Neutrino Detector, the project calls for placing an array of light sensors at a depth of five kilo- meters under the ocean surface. The detecting medium is the seawater itself: when a neutrino interacts with a (40)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. The five kilometers of sea- water above the sensors will shield them from the interf- ering fects of other high-energy particles raining down (45) through the atmosphere. The strongest motivation for the DUMAND project is that it will exploit an important source of information about the universe. The extension of astronomy from visible light to radio waves to x-rays and gamma rays (50) never failed to lead to the discovery of unusualobjects such as radio galaxies, quasars, and pulsars. Each of these discoveries came as a surprise. Neutrino astronomy will doubtless bring its own share of surprises.1. Which of the following titles best summarizes the passage as a whole?

(B) Neutrino astronomy will be abandoned if the DUMAND project fails.
(C) Neutrino astronomy can be expected to lead to major breakthroughs in astronomy.
(D) Neutrino astronomy will disclose phenomena that will be more surprising than past discoveries.

(E) The infrequency of their interaction with other matter
8. According to the passage, the interaction of a neutrino with other matter can produce
(A) particles that are neutral and massive
(B) a form of radiation that permeates the universe
(C) inaccurate information about the site and
circumstances of the neutrino’s production
