UFOs are unidentified flying objects, but no one really knows what they are. Many researchers(called "ufologists")have theories about what UFOs might be, but because no one can examine a UFO in a scientific laboratory, all of these ideas are really only educated guesses.
【C1】______
All kinds of people see UFOs. It does not matter whether you are rich or poor, educated or uneducated, young or old. In fact, many people who report seeing UFOs were not even looking for them when they had their sighting.
【C2】______
UFOs come in all shapes and sizes. Some are only small spots of light that move in strange patterns across the night sky. These are called nocturnal lights(NLs)and are the most commonly reported type of UFO. Nocturnal lights are not really very interesting because the witness can see little detail; without details, UFO researchers cannot learn anything new. Faraway objects, often disk- or saucer-shaped, seen in the daytime are called daylight disks(DDs).
When UFOs approach much nearer to witnesses(within 500 feet), these sightings are called close encounters.
【C3】______
The reported speed of UFOs varies dramatically. UFOs can hover silently for a long time then instantaneously fly off at great speeds—certainly much faster than conventional aircraft. They can move slowly across the sky, or perform unbelievable maneuvers, such as right angle turns, at incredibly high speeds. We do not know what powers UFOs, or why they have such maneuverability.
There are few unquestionably authentic pictures of UFOs. Many so-called UFO photographs are really natural phenomena(such as strangely shaped clouds)or are light leaks in the camera or flaws that were introduced when the film was developed.
【C4】______
At present, the United States government does not officially investigate UFO sightings, although there is some evidence suggesting that various governmental agencies continue to maintain a secret interest in the subject.
【C5】______
[A]Because we do not know for certain that UFOs are spacecraft, we cannot be sure aliens are visiting the earth from other planets. Many ufologists argue that there is enough evidence to show that UFOs are really spacecraft operated by intelligent aliens.
[B]However, we can offer a definition of UFOs that you may find useful when you study the subject. Namely, a UFO is the reported sighting of an object or light seen in the sky or on land, whose appearance, trajectory, actions, motions, lights, and colors do not have a logical, conventional, or natural explanation, and which cannot be explained, not only by the original witness, but by scientists or technical experts who try to make a common sense identification after examining the evidence.
[C]Within certain distance, witnesses report seeing UFOs that are shaped like saucers, boomerangs, spheres, diamonds, cigars, triangles, or other strange shape. They have bright lights, sometimes white or red, other times multicolored.
[D]However, the chances for seeing a UFO are greater for those people who live in small towns or in the country and are outside late at night.
[E]Many UFO researchers argue that UFOs have appeared throughout history. There are many myths, legends, and stories that tell of strange things seen in the sky or beings who came from the sky to help humans develop civilization.
[F]Some photos are deliberate hoaxes made by people who want you to believe they have seen UFOs; for any number of reasons, such as fame, money, or to promote a religious or philosophical viewpoint.
[G]However, there are many people of different occupations, who are enthusiastic about UFO. They are called urologists. They maintain their enthusiasm and take it as their lifelong hobby. Many of them admit that their interest in UFOs is sparked by seeing a UFO or reading UFO stories. Their work is and will contribute a lot to the man’s revelation of the mystery.

答案
D
解析
此项有个转折词however,很明显是承接第二段的内容,讲能否看到UFO与客观条件的确有很大关系,生活在乡村或者小城镇的人,夜晚在户外看到UFO的可能性较大。
