Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.
A survey is a study, generally in the form of an interview or a questionnaire, which provides information concerning how people think and act. In the United States, the best-known surveys are the Gallup poll and the Harris poll. As anyone who watches the news during presidential campaigns knows, these polls have become an important part of political life in the United States.
North Americans are familiar with the many "person on the street" interviews on local television news shows. While such interviews can be highly entertaining, they are not necessarily an accurate indication of public opinion. First, they reflect the opinions of only those people who appear at a certain location. Thus, such samples can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which area the news people select. Second, television interviews tend to attract outgoing people who are willing to appear on the air, while they frighten away others who may feel intimidated by a camera. A survey must be based on a precise, representative sampling if it is to genuinely reflect a broad range of the population.
In preparing to conduct a survey, sociologists must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand it. It must also be specific enough so that there are no problems in interpreting the results. Even questions that are less structured must be carefully phrased in order to elicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately.
There are two main forms of surveys: the interview and the questionnaire. Each of these forms of survey research has its advantages. An interviewer can obtain a high response rate because people find it more difficult to turn down a personal request for an interview than to throw away a written questionnaire. In addition, an interviewer can go beyond written questions and probe for a subject's underlying feelings and reasons. However, questionnaires have the advantage of being cheaper and more consistent.
As it can be inferred from the passage, sociologists can be frustrated when _________.
A.respondents often do not complete and return questionnaires
B.questionnaires are too difficult to read
C.questionnaires are too expensive and difficult to distribute
D.respondents are too eager to supplement questions with their own options

HOW WILL WE LIVE IN 2035?
Welcome to life in the future!
You get up in the morning and look into the mirror. You've just had an anti-aging treatment, so your face looks youthful. In 2035, many people your age could live to be 150, so at 60, you're not old at all.
Science has also found amazing ways to keep people healthy. There are nanotechnology treatments for many illnesses, including cancer. And if any part of your body is not healthy, you can "grow'' a new one in a laboratory.
As you get dressed, you say to your shirt, "Turn red." It becomes red. In 2035, “smart clothes" contain nanoparticles that carry electricity. So you can program clothes to change colors or patterns.
On the way to the kitchen, you want to call a friend. Your cell phone is by the window because the material it's made of takes in energy from the sun. But you don't need to pick up the phone. You can just touch your jacket sleeve to make the call.
These are just some examples of nanotechnology all around you. "Your whole body and surroundings [will] become part of the same network," says scientist Ampy Buchholz.
It's breakfast time. You reach for the milk, but a voice says, "Don't drink that!" Your fridge is reading a computer chip on the milk. Every item from the grocery has a chip. Your fridge knows the milk is old, and tells the store you need new milk.
Finally, it’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go, and soon you will be there.
So, will all these predictions come true? Perhaps the future is much closer than we think.
The word “it’s” refers to_____.
A.the window
B.the cell phone
C.the sun
D.the material
