Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: When an ant dies, other ants move the dead insect out. Sometimes, the dead ant get moved away very soon--within an hour of dying. This behavior is interesting to scientists, who wonder how ants know for sure--and so soon--that another ant is dead. One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, "I'm dead--take me away." But there's a _ to Choe's discovery. Choe says that the living ants--not just the dead ones--have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it's telling other ants that it's dead. What keeps ants from dragging away the living ants?Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, "Wait--I'm not dead yet." So Choe's research turned up two sets of chemical signals in ants: one says, "I'm dead," and the other set says, "I'm not dead yet." Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive. Choe suspects that when an Argentine ant dies, the chemical that says "Wait-I'm not dead yet" quickly goes away. Once that chemical is gone, only the one that says "I'm dead" is left. "It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard, not because its body releases new unique chemicals after death," said Choe. When other ants detect the "dead" chemical without the "not dead yet" chemical, they drag away the body. Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests. The ants' removal behavior is important to the... Options: A Because it is easier to manage the living. B Because it can save money to deal with the waste. C Because it can provide more space for the living. D Because it can keep the living from suffering disease. Answer: D Because it can keep the living from suffering disease. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: It was a late Wednesday night when the dreading phone call reached our home. I sat up, somehow terrified, so I could hear the phone call better. To my surprise, I heard my mom burst into tears. "Get the car, Dean! Andrea has been in a car accident." _ We got to the hospital, but were not allowed to see Andrea. The next morning, after wearing masks, we were allowed to go to the ICU to see Andrea. Well, the least I could say was that everything was injured in her body and she lost all of her memories. It was a fatal accident. Over the next two months, I lived more at the hospital than I did at my house. I watched as Andrea worked so hard to gain back everyday motor skills. She never once complained or pitied herself; her determined spirit was shining through. After two weeks in the ICU and two months of the regular hospital treatment, Andrea was able to come home. She missed several months of school, so it was hard for her to catch up. Andrea had tasks to accomplish, and no matter how hard it was, she stuck with them until the job was done. Though busy with dealing with pain and therapy, she always found time to love and play with me. I'll never forget the impact that this incident made on my life. I admire her strong-willed personality and her determined spirit. Today she is perfectly normal, despite the scars and the pins holding her leg in place. I couldn't ask for a better sister, hero, or best friend. Options: A had to give up all her studies B stopped playing with the writer. C refused to be accompanied. D showed unbelievable strength. Answer: D showed unbelievable strength. Question:

A: During the treatment, Andrea _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Studies have documented that smiling is a universal and effective way to lift mood. But in the latest research on the power of the smile, researchers led by Marcus Munafo of the University of Bristol in England found that even seeing smiles on the faces of others can have a profound effect on a person's tendency toward violence or aggression -- that is, as long as that person recognizes the smile as one of happiness, and not as a sneer . Munafo and his colleagues conducted a series of experiments involving normal adults and highly aggressive teens referred to a youth program, either by educational authorities or the courts. About 70% of the teens already had a criminal record. In the first experiment, 40 healthy adults, aged 1830, looked at facial expressions on the computer ranging from happy to angry with increasingly difficult ones to _ in between. Participants were asked how angry they felt and then had to rate the images as displaying either happiness or anger -- there was no option for "unclear" or "unable to tell". From these ratings, the scientists could generate a score of their preference toward happiness or anger. Previous research found that aggressive people -- including violent offenders -- tend to consider even a common expression as an unfriendly one. "You looking at me?" can easily turn a simple question into a tragic fight. Based on their original scores, half of the participants were then told by the computer that some of the unclear faces that they had rated as angry should have been scored as happy. This was intended to guide them toward judging the inbetween faces more positively. The other 20 received feedback that simply proved their first choices, creating a control group. After this training, both groups were tested again and the group that received the biased feedback shifted its ratings of unclear faces toward the happy side. Participants were also asked to rate their level of angry feelings again after completing the second round of testing. Those who were trained to consider... Options: A field investigation B case study C observation and analysis D experiment and comparison Answer: D experiment and comparison Question:
A:
The method Munafo and his colleagues used in their research is _ .
