input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Students who date in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia. "Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.[: _ Z _ X _ X _ K] Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade. Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students' academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school. "At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills," according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters. "Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying." "Dating should not be considered a ceremony of growth in middle school," Orpinas concluded. Options: A followed a group of students of 6th and 12th grade B completed a survey and a report each year C completed questionnaires about the students' academic efforts D found that the students' study skills have connection with their frequency of dating Answer: D found that the students' study skills have connection with their frequency of dating Question:???
output answer: When doing his study, Orpinas _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: Every culture has a recognized point when a child becomes an adult, when rules must be followed and tests passed. In China, although teenagers can get their ID cards at 16, many only see themselves as an adult when they are 18. In the US, where everyone drives, the main step to the freedom of adult life is learning to drive. At 16, American teens take their driving test. When they have their license, they drive into the grown-up world. "Nobody wants to ride the cheese bus to school," said Eleanor Fulham, 17. She brought the pressure back to memory, especially from kids from wealthier families. "It's like you're not cool if you don't have a car," she said. According to recent research, 41% of 16 to 19-year-olds in the US own cars, up from 23% in 1985. Although, most of these cars are bought by parents, some teens get part-time jobs to help pay. Not all families can afford cars for their children. In cities with subways and limited parking, some teenagers don't want them. But in rich suburban areas without subways, and where bicycles are more for fun than transportation, it is strange for a teenager not to have a car. But police say 16-year-olds have almost three times more accidents than 18 and 19-year-olds. This has made many parents pause before letting their kids drive. Julie Sussman, of Virginia, decided that her son Chad, 15, will wait until he is 17 to apply for his learner's permit. Chad said he has accepted his parents' decision, although it has caused some teasing from his friends. "They say that I am unlucky," he said, "But I'd rather be alive than driving, and I don't really trust my friends on the road, either." In China, as more families get cars, more 18-year-olds learn to drive. Will this become a big step to becoming an adult? Options: A he might run into his friends if he drove B he didn't agree with his friends C he might not be safe if his friends drove D he was afraid that his friends might well lie to him Answer: C he might not be safe if his friends drove Question:
----
Answer: When Chad said "I don't really trust my friends ...", he meant that _

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: WHEN there are some strangers in front of us, which of them will we trust? According to a new study in the online PloS One (<<*>> ), people make their decisions to trust others largely based on their faces. Your appearance can do a lot for you, especially if you are in the financial industry. The more trustworthy you look, the more likely people will buy what you're selling. Researchers from Britain's University of Warwick Business School, University College London, and Dartmouth College, US, did a number of experiments. The research team used computer software to make 40 faces, from the least to the most trustworthy-looking. The study said that the difference between a trustworthy face and one that isn't as trustworthy comes from features that look slightly angry or slightly happy, even when the face is at rest. However, a slightly happy face is more likely to be trusted. Researchers gave participants some money and asked them which face they trusted to invest the money for them. Then researchers gave some good and bad information about the people with these faces, and asked the participants again whom they trusted. The results showed that even if they got different information, the participants didn't change their choices. They were still more likely to invest their money with the more trustworthy-looking faces. Chris Olivola, one of the study's authors, said in the University of Warwick's press release: "It seems we are still willing to go with our own instincts about whether we think someone looks like we can trust them. The temptation to judge strangers by their faces is hard to resist." Options: A A sad face. B A smiling face. C A crying face. D An angry face. Answer: B A smiling face. Question:

Answer:
According to the study, which of the following faces is most likely to be trusted?
