Q: Read the following article and answer the question. Article: Recent developments in astronomy have made it possible to detect planets in our own Milky Way and in other galaxies. This is a major achievement because,in terms,planets are very small and do not give out light. Finding planets is proving hard enough, but finding life on them will prove _ more difficult. The first question to answer is whether a planet can actually support life. In our own solar system,for example,Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions,and even here it has taken more than four billion years for plant and animal life to evolve . Whether a planet can support life depends on the size and brightness of its star, that is its "sun". Imagine a star up to twenty times larger, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life. On the contrary, if the star were small,the life--supporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. But how would we fund such a planet? At present, there is no telescope in existence that is capable of detecting the presence of life. _ . It is impossible to look for life on another planet using earth--based telescopes. Our own warm atmosphere and the heat generated by the telescope would make it impossible to detect objects as small as planets. Even a telescope in orbit round the earth like the very successful Hubble telescope,would not be suitable because of the dust particles in our solar system. A telescope would have to be as far away as the planet Jupiter to look for life in outer space because the dust becomes thinner the further we travel towards the outer edges of our own solar system. Once we detected a planet,we would have to find a way of blocking out the light from its star, so that we would be able to "see" the planet properly and analyze its atmosphere. In the first instance, we would be looking for plant life,rather than "little green men" .... Question: It can be inferred from the passage that---- Answer:

OPTIONS:
- the Hubble telescope is suitable for any space exploration
- we humans will be visited by little green men
- finding life on another planet will be shocking news
- no achievement has been made in astronomy

A: finding life on another planet will be shocking news

Q: Read the following article and answer the question. Article: A man accused of failing to return more than 700 children's books to five different libraries in the county was released from prison after a book publisher agreed to post his bond of $1,000.The publisher said."There's a story here.This is a man who loves books.He just can't let go of them.He hasn't stolen a single book.So what's the crime ? We think that Mr.Banish has story to tell.We plan to publish his story." When asked why he didn't return the books, Mr.Banish said,"Well,how could I? They became family to me.I was afraid to return them,because I knew that kids or dogs would get hold of these books and chew them up,throw them around,tear the pages,spill soda on them,get jelly on them,and drown them in the toilet. He continued,"Books are people,too! They talk to you,they take care of you,and they enrich you with wisdom,humor and love.A book is a guest in my home.How could I kick it out? I repaired tor n pages.I dusted them with a soft clean cloth.I turned their pages so they could breathe and get some fresh air." "Every week I reorganized them on their shelves so they could meet new friends,My books were HAPPY books.You could tell just by looking at them.Now they're all back in the libraries,on the lower shelves,on the floors,at the mercy of all those runny-nosed kids I can hear them calling me.I need to rescue them.Excuse me.I have to go now." Question: From the passage we can learn that the man is Answer:

OPTIONS:
- a thief
- a writer
- crazy about books
- unfortunate

A: crazy about books

Q: Read the following article and answer the question. Article: Even though orbiters have eyed it from space and landers have rumbled across its surface, Mars still has more secrets to reveal. Two findings emerged this week: the possibility of an active glacier far from the planet's poles and evidence that sulfur--rather than carbon--was the element driving the planet's warmer climate long ago. Both discoveries could force some rethinking about Martian evolution and dynamics--and maybe even provide insights about Earth's past. The glacier discovery was announced Wednesday by the European Space Agency (ESA). A high-resolution stereo camera aboard ESA's Mars Express spacecraft spotted the feature in a region called Deuteronilus Mensae, located in the mid-north latitudes of the planet. The Mars Express science team drew the preliminary conclusion that the material in the feature is water ice and that it accumulated as recently as 10,000 years ago, probably from an underground source. Other deposits of water ice have been mapped at the martian poles, but they're much bigger and are millions of years old. The find is a surprise because the prevailing view is that any water reaching the martian surface from underground quickly evaporates and eventually drifts into space. Yet all of the physical characteristics of the feature are "consistent with that of a glacier," says geologist and team member Ronald Greeley of Arizona State University in prefix = st1 /Tempe. Meanwhile, in the 21 December issue of Science, a team from HarvardUniversityand the Massachusetts Institute of Technology offers a possible solution for the curious absence of carbon-based minerals on Mars. A buildup of carbon dioxide in the ancient martian atmosphere supposedly produced enough of a greenhouse effect to allow liquid water to flow for a time on the surface. The problem is that such a process should have deposited ample carbon-containing minerals on the planet's surface--something that hasn't been found. So the researchers have come up with a new explanation: Large amounts of sulfur dioxide(SO2) in... Question: What is probably the title of the passage? Answer:

OPTIONS:
- The red planet still packs surprises
- The possibility of a glacier on Mars
- The main key to the warmth on Mars
- Water may exist on the mysterious planet

A:
The red planet still packs surprises
