¡¡¡¡4. According to the passage£¬ one advantage that neutrinos have for studies in astronomy is that they

¡¡¡¡£¨A£© have been detected for the last twenty-five years

¡¡¡¡£¨B£© possess a variable electric charge

¡¡¡¡£¨C£© are usually extremely massive

¡¡¡¡£¨D£© carry information about their history with them

¡¡¡¡£¨E£© are very similar to other electromagnetic particles

¡¡¡¡5. According to the passage£¬ the primary use of the apparatus mentioned in lines 24-32 would be to

¡¡¡¡£¨A£© increase the mass of a neutrino

¡¡¡¡£¨B£© interpret the information neutrinos carry with them

¡¡¡¡£¨C£© study the internal structure of a neutrino

¡¡¡¡£¨D£© see neutrinos in distant regions of space

¡¡¡¡£¨E£© detect the presence of cosmic neutrinos

¡¡¡¡6. The passage states that interactions between neutrinos and other matter are

¡¡¡¡£¨A£© rare

¡¡¡¡£¨B£© artificial

¡¡¡¡£¨C£© undetectable

¡¡¡¡£¨D£© unpredictable

¡¡¡¡£¨E£© hazardous

¡¡¡¡7. The passage mentions which of the following as a reason that neutrinos are hard to detect£¿

¡¡¡¡£¨A£© Their pervasiveness in the universe

¡¡¡¡£¨B£© Their ability to escape from different regions of space

¡¡¡¡£¨C£© Their inability to penetrate dense matter

¡¡¡¡£¨D£© The similarity of their structure to that of nucleons

¡¡¡¡£¨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

¡¡¡¡£¨D£© charged particles and light

¡¡¡¡£¨E£© a situation in which light and other forms of electromagnetic radiation are blocked

¡¡¡¡9. According to the passage£¬ one of the methods used to establish the properties of neutrinos was

¡¡¡¡£¨A£© detection of photons

¡¡¡¡£¨B£© observation of the interaction of neutrinos with gamma rays

¡¡¡¡£¨C£© observation of neutrinos that were artificially created

¡¡¡¡£¨D£© measurement of neutrinos that interacted with particles of seawater

¡¡¡¡£¨E£© experiments with electromagnetic radiation
