Which of the following is true according to the text？
听力原文： In the field of marketing，consumer goods are classed according to the way in which they are purchased．The two main categories are convenience goods and shopping goods．Two lesser types are specialty goods and unsought goods．
People do not spend much time shopping for convenience items such as groceries，newspapers，toothpaste，razor blades，aspirin，and candy．The buying of convenience goods may be done routinely，as some families buy groceries once a week．Such regularly purchased items are called staples．Sometimes convenience products are bought on impulse，for example，someone has a sudden desire for an ice cream sundae on a hot day．Or they may be purchased as emergency items．
Shopping goods are items for which customers search．They compare prices，quality，and styles，and may visit a number of stores before making decisions．Buying an automobile is often done this way．
Shopping goods fall into two classes：those that are perceived as basically the same and those that are regarded as different．Items that are looked upon as basically the same include such things as home appliances，television sets，and automobiles．Having decided on the model desired，the customer is primarily interested in getting the item at the most favorable price．Items regarded as inherently different include clothing，furniture，and dishes．Quality，style. and fashion will either take precedence over price，or they will not matter at all．
Specialty goods have characteristics that impel customers to make special efforts to find them．Price may be no consideration at all. Specialty goods can include almost any kind of product．Normally，specialty goods have a brand name or other distinguishing characteristics．
Unsought goods are items a consumer does not necessarily want or need or may not even know about．Promotion or advertising brings such goods to the consumer's attention．The product could be something new on the market or it may be a fairly standard service．such as life insurance．for which most people will usually not bother shopping．
According to the speaker，what are convenience goods？

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and respectable occupations. Personal consultants give better advice for finding jobs. Even judges are softer on attractive defendants (被告). But in the executive (行政的) circle, beauty can become a liability.
While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman.
Handsome male executives were perceived as having more integrity than plainer men; effort and ability were though to account for their success.
Attractive female executives were considered to have less integrity than unattractive ones; their success was attributed not to ability but to factors such as luck.
All unattractive women executives (行政长官) were though to have more integrity and to be more capable than the attractive female executives. Increasingly, though, the rise of the unattractive overnight successes was attributed more to personal relationships and less to ability than was that of attractive overnight successes.
Why are attractive women not thought to be able？ An attractive woman is perceived to be more feminine (女性) and an attractive man more masculine (男性) than the less attractive ones. Thus an attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally masculine position appears to lack the "masculine" qualities required.
This is true even in politics. "When the one clue is how he or she looks, people treat men and women differently," says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduates to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were then told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.
The results showed that attractive males utterly defeated unattractive men, but the women who had been ranked most attractive invariably received the fewest votes.
The word "liability (Paragraph 1, Line 5)" most probably means "______."
