Read the following article and select the best answer. Article: Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives -either recorded or real-may even prevent elephants from damaging farmer's crops. In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away. Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family. From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place. Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away. Question: We know from the passage that elephants may be frightened of _ . - loud noises - some crops - video cameras - angry bees
angry bees

Q: Read the following article and select the best answer. Article: While income worry is a rather common problem of the aged, loneliness is another problem that aged parents may face. Of all the reasons that explain their loneliness, a large geographical distance between parents and their children is the major one. This phenomenon is commonly known as "Empty Nest Syndrome" . In order to seek better chances outside their countries, many young people have gone abroad, leaving their parents behind with no clear idea of when they will return home. Their parents spend countless lonely days and nights, taking care of themselves, in the hope that someday their children will come back to stay with them. The fact that most of these young people have gone to Europeanized or Americanized societies makes it unlikely that they will hold as tightly to the value of duty as they would have if they had not left their countries. Whatever the case, it has been noted that the values they hold do not necessarily match what they actually do. This geographical and cultural distance also prevents the grown-up children from providing response in time for their aged parents living by themselves. The situation in which grown-up children live far away from their aged parents has been described as "distant parent phenomenon", which is common both in developed countries and in developing countries. Our society has not yet been well prepared for "Empty Nest Syndrome". Question: According to the passage, the loneliness of aged parents is mainly caused by _ . - their earlier experience of feeling lonely - the unfavorable living conditions in their native countries - the common worry about their income - the geographical distance between parents and children
A: the geographical distance between parents and children
