Given the task definition, example input & output, solve the new input case.
In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
Example: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.
Question: Researchers did experiments on kids in order to find out _ .
Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness
Output: B
It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. So, B is the correct answer.

New input case for you: Article: Located along California's San Andreas Fault, the city of San Francisco is likely to take precautions(,) in the event of the next big earthquake. According to aNew York Timesreport, emergency planners in San Francisco are not only thinking of human evacuation(,) plans in the event of an earthquake, but also of how to care for pets during a natural disaster. Ideally, the planners will be able to train pet-disaster responders who work to evacuate dogs, cats and other household pets from the disaster site to one of the 125 temporary animal shelters that will be set up or, if the pet is injured, it will be brought to an emergency animal medical unit where there will be people on hand to tend to the pet's injury. The city's "no-pets-left-behind" policy results from the great number of pet deaths during the destruction of Hurricane Katrina. As emergency responders arrived to rescue people isolated in their homes during Katrina, hurricane victims were told that they could not take their pets along with them when evacuating; thus, many pet owners were forced to make the heart-breaking decision to save themselves while leaving their pets behind to perhaps meet their deaths. Since then, the U.S. has passed the Pets Evacuation and Transportation Standards Act of 2006, allocating federal funds for animal disaster planning projects. Yet, not all counties are as progressive as San Francisco has been in the effort to protect pets in the event of a natural disaster. Pets are after all, a large part of San Francisco's population -- overnumbering the number of school age children in the city. Over the last three years, San Francisco has received $350,000 in federal funds _ to animal disaster preparedness efforts in order to protect animals in the case of a disaster such as an earthquake. The city is still working on obtaining $300,000 to pay for an emergency animal unit. Until then, animal lovers in San Francisco will continue to work to ensure that pets are never an afterthought when it comes to rescues during earthquakes or other life threatening situations.
Question: What do we know about Hurricane Katrina?
Options: (A) A great number of pets died during Hurricane Katrina. (B) San Francisco's "no-pets-left-behind" policy had been made before Hurricane Katrina. (C) The pet owners chose to sacrifice themselves in order to save their pets. (D) Emergency responders failed to rescue the hurricane victims.
Output:
A
