Read the following article and select the best answer. Article: It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who pose a threat and those who do not. In Kenya, researchers found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus pose a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants. In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all. Clothing color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively toward the red clothing. The researchers believe that the elephants' emotional reactions are due to their different interpretations of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive. Question: According to the passage, which of the following statements is TRUE about Kamba and Maasai people? - Maasai people are a threat to elephants. - Kamba people raise elephants for farming. - Both Kamba and Maasai people are elephant hunters. - Both Kamba and Maasai people traditionally wear red clothing.
(Answer)
Maasai people are a threat to elephants.

Read the following article and select the best answer. Article: The first people who gave names to hurricanes were those who knew them best -- the people of Puerto Rico. The small island of Puerto Rico is in the West Indies, off the coast of Florida. This is where all the hurricanes begin that strike the east coast of the United States. Often they pass near Puerto Rico or cross it on their way north. The people of Puerto Rico expect some of these unwelcome visitors every year. Each one is named after the Saint's Day on which it arrives. Two of the most destructive storms were the Santo Ana in 1840 and the San Ciriaco in 1899. Giving girls' names to hurricanes is a fairly new idea. It all began with a story called "Storm", written by George Stewart in 1941. In it a weatherman amused himself by naming storms after girls he knew. He named one Maria. The story describes how she Maria grew and developed, and how she changed the lives of people when she struck the United States. Weathermen of the U.S. Army and Navy used the same system during World WarII. They were studying weather conditions over the Pacific Ocean. One of their duties was to warn American ships and planes when a storm was coming. Whenever they spotted one, they gave it a girl's name. The first one of the year was given a name beginning with [A]. The second one got a name beginning with [B]. They used all the letters from A to W, and still the storms kept coming. They had to use three lists from A to W to have enough names to go around. This was the first list of hurricane names that followed the alphabet. It served as a model for the system the Weather Bureau   introduced in 1942. Before 1950 the Weather Bureau had no special system for naming hurricanes. When a hurricane was born down in the West Indies, the Weather Bureau simply collected information about it. It reported how fast the storm was moving and where it would go next. Weather reports warned people in the path of the hurricane, so that they could do whatever was necessary to protect themselves. This system worked out fine as long as weather reports... Question: The Weather Bureau began naming hurricanes because it would help them    _   . - collect information more rapidly - warn people more efficiently - make use of military   records - remember them
(Answer)


assistant: warn people more efficiently
