Read the following article and select the best answer. Article: Yesterday I started the Year of Giving, my first day of a year-long journey into exploring the act of giving and the meaning of charity. I chose December 15 as the starting date, which marked three years since my mother died from heart disease. She was one of the most generous people that I have ever known. She always thought of others first and certainly serves as an inspiration to me. I had a rather busy day yesterday, ironic for someone who is unemployed right now. In the morning I went to the gym, and unsuccessfully got the phone call from the unemployment office for some job searching. Before I knew it, it was noon. I grabbed a quick lunch and rushed down to a meeting. On my way to Connecticut, I wondered if I would see someone that I would feel forced to give my first $10 to. I was running late and decided to do it afterwards. After the meeting I had about half an hour to find the first person of my Year of Giving! I decided to check out Dupont Circle. I had met a guy there named Jerry once and thought he would willingly accept my first $10. He wasn't there, but I did see a man sitting by himself who looked really lonely, so I approached him. Now I had to figure out what I was going to say. I think I said something like, "Hi, can I sit down here?" "I would like to know if I could give you $10?" He asked me to repeat what I had said. I did, then he looked at me funny, got up and left. I then started walking south where I spotted a man standing by the bus stop on Connecticut Ave. He appeared to be in his 60s. I don't know what drew me to him, but I thought I would make my second attempt. I was a bit nervous and asked him which bus came by that stop. Then I explained that I was starting a year-long project to give $10 to someone every day and that I wanted to give my $10 for today to him. The gentleman, I later found out that his name was Ed, responded without hesitation that he could not accept my offer and that there were many people more deserving the money than him. This was exactly one of the things... Question: The author set the starting date on December 15 to _ . - help the charity - remember his mother - make an exploration - fulfill a wish of his mum
remember his mother

Read the following article and select the best answer. Article: Agricultural experts met in Ethiopia last week to discuss ways to help sub-Saharan Africa become a major producer of wheat. The area traditionally produced little wheat, while North Africa was the grain basket. Wheat production fell sharply in sub-Saharan countries during the 1980s. In the 1960s, attempts were made to grow wheat in sub-Saharan Africa, including South Africa and Zimbabwe. But those countries found it was less costly to import wheat from Europe and the United States. Another problem is that Africa's wheat farms were often far from population centers. There also were transportation issues. And some lowlands were not a good place to grow wheat. Hans Joachim Braun,one of the experts, says now is a good time to increase wheat production. In the last four years we have seen three major price hikes, where the wheat price and other staple process exploded. And that puts a big, big bill on countries which are depending on wheat imports, and Africa is the biggest wheat importer. He also says demand for wheat in sub-Saharan Africa is growing faster than for any other crop. With higher income people would like to have more diversified food. But that is possible not the most important one. The most important one is that there is a tremendous migration of in particular male labor to the cities. And wheat products are convenient food because you can easily buy it. It's easy to process and you also can store it for a few days, which is different from some of the maize and rice products. There are three possible challenges for growing more wheat in Africa: climate change, disease and pests, like insects. Mr. Braun says rising temperatures should not have a major effect on wheat. In fact, he says, it could help wheat grow in areas with high rainfall totals. As for fighting disease and pests, experts suggest growing more resistant crops. In addition, railroads and roads would have to be improved so large amounts of wheat could be moved to large markets. Question: Wheat price exploding indicates _ . - sub-Saharan countries need to increase wheat production badly - sub-Saharan countries have to issue more money - sub-Saharan countries should grow more Corn - importing much wheat is urgent
(Answer)
sub-Saharan countries need to increase wheat production badly

Read the following article and select the best answer. Article: If you are afraid of the dark,it's not a big deal.It's perfectly normal to feel afraid After all,animals do too. "Fear matters,"says Karen Warkentin,an ecologist."It's a good thing," she adds, "because fear makes you do things that keep you alive." Like kids,many animals experience fear and they respond to the feeling in variety of ways.A frightened turtle pulls its head and legs inside its shell.A small fish will swim away when a big,hungry fish approaches. Some animals respond to fear in ways you might not expect.The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red--eyed tree frogs in Costa Rica. In this species,female frogs attach jellylike clumps of their eggs to the undersides of leaves.The leaves hang on branches that dangle over ponds.After they hatch from the eggs,the tadpoles then fall into the water,where they eventually grow into adult frogs. Tree frog eggs usually grow for 6 days before hatching.If they sense that a hungry snake is about to attack,however,they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim,by falling into the water early,the tadpoles can escape. If hatching early helps protect red--eyed tree frogs from snakes,you might wonder why their eggs don't always hatch sooner.It turns out that hatching early brings its own danger.Once tadpoles land in the water,hungry fish and other animals like to eat them too.Staying in their eggs for a full 6 days,then,allows frog embryos to grow big and strong.This extra growth improves their chances of surviving in the water. Question: It can be inferred from the passage that fears _ . - help animals grow bigger and stronger - are less common among young animals - help animals move a lot to fit the environment - are more or less important in order for animals to survive
are more or less important in order for animals to survive
