Input: Consider Input: Article: Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more food. In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops. Wambugu went to war against the virus. Her research for a way to save the sweet potatoes led to a lab in St. Louis, Missouri. The lab mainly works on genes , the chemical "computer programs" found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering. Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes. That's just the beginning, Wambugu believes. Genetically modified foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry.
Question: The text is written mainly to _ .
Options: (A) tell us sweet potatoes are in danger of being attacked by a virus (B) introduce Wambugu's contribution to genetic engineering (C) introduce a new way of killing plant viruses (D) tell how hard Wambugu worked in her lab for three years
Asnwer: B

Output: Yes

Input: Consider Input: Article: An air of anxious uncertainty spread throughout the small Indian camp as the sun dawned that morning. Some braves gathered beside a smoking campfire. Murmuring sounds could be heard as they talked quietly. Women nervously performed their domestic tasks, preparing a small meal. Several sad, old men sat mute, their morale very low. The camp was pitched at the edge of a deep valley--so deep that one could barely see the calm water at the bottom. The Indians had been taken by surprise and were surrounded and attacked by enemy forces. They fought bravely, but they were degraded by defeat. Their homes were destroyed. Those who had survived had been pursued by the enemy. The chase had lasted for days. Persuaded by their leaders to press on, they had made a wrong turn. Their _ journey ended at the edge of a valley--a desperate situation. Before them was a great hole in the earth. Behind them was the enemy. No wonder they were frozen with fear. Where could they go? Just when no choice seemed available to them, several young braves ran into camp. With great excitement they reported seeing a stone bridge across the valley, just a short distance from camp. Most of the tribe discounted this wild story. However, a few hurried to the spot to see for themselves. Seeing was believing! Indeed there was a stone bridge, great enough to accommodate many people and their horses. Without hesitation the people gathered up their children and the belongings they had and hurried across the bridge. Enemy braves watched from a nearby cliff. It was obvious that the Great Spirit was on the side of the defeated. The enemy did not follow. Safe on the other side of the valley, the wanderers thanked the Great Spirit for providing the vital link. They had escaped their enemies. For hundreds of miles around, Indian people heard about the miraculous stone bridge. From this incident it was clear that the Great Spirit defends weak people. Many came from near and far to see the magnificent stone bridge. You, too, can see this bridge and even ride across it in a car--in southwestern Virginia.
Question: Faced with the desperate situation, some Indians in the camp _ .
Options: (A) tried to persuade their leaders to give in to the enemies. (B) were still as cheerful as before. (C) still remained fearless and loyal to their leaders. (D) were in very low spirits.
Asnwer: C

Output: No

Input: Consider Input: Article: 7 ways a government shutdown will affect your daily life (CNN) -- Democrats and Republicans were unable to resolve their differences over Obamacare and now the government is shut down. The two previous shutdowns -- 1995 and early 1996 -- cost the country $1.4 billion. But what will the shutdown mean for you? Here are 7 ways the government shutdown will affect you. 7. Vacation all I ever wanted: Need to get away? Well, you can't. At least not to national parks. Or to national zoos. Or to national museums. They'll be closed. Were you thinking more along the lines of a trip to France? If you don't already have a passport, you might not get your blue book in time. The last time the government shut down, 200,000 applications for passports went unprocessed. 6. If you drive a car, I'll tax the street: You may be thinking, "No functioning government, no need to pay taxes." Think again. The Man would continue to collect taxes. U.S. bonds would still be issued. And other essential banking functions will go on. 5. Wait a minute, Mr. Postman: You know that whole "Neither snow, nor rain, nor heat, nor gloom of night" thing? Apparently, the U.S. Postal Service works through shutdowns as well. Sorry, you won't catch a break from the junk mail. 4. I want a new drug: Oh, the irony . Republicans still want to _ delay or otherwise withdraw gradually at Obamacare in exchange for funding the government. But the health care act at the center of this storm would continue its process during a shutdown. That is because its funds aren't dependent on the congressional budget process. 3. Pass the ammunition : Not so fast. A shutdown would affect the Bureau of Alcohol, Tobacco, Firearms and Explosives. Translation: That gun permit you wanted processed won't happen anytime soon if this goes on for a while. 2. Money (that's what I want): Well, if you owned a small business and needed a loan from the government, you would have to wait, depending on how long this lasts. If you were planning to buy a house and needed a federal loan, you would have to wait. 1. I'm proud to be an American: Perhaps the biggest hit would be to the collective psyche . America is the largest economy in the world and a beacon for how democracy ought to work. A recent CNN Research Corporation found that 51% would blame Republicans for the shutdown. The United States has operated without a budget since 2009 and has avoided a government shutdown with last-minute deals. Not only did the government run out of money on Tuesday, but the nation is set to hit its borrowing limit and potentially default on its debt in mid-October. Together, they serve as a double whammy .
Question: When the government's shut down, what can the Americans do?
Options: (A) Apply for a gun permit. (B) Apply for a new passport. (C) Apply for a loan. (D) Pay taxes.
Asnwer: D
Output: Yes
