In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.

[Q]: Article: On October 23, 2011, David Pologruto, a high school physics teacher, wasstabbed by his smart student Jason Haffizulla. Jason got straight A's and was determined to study medicine at Harvard, yet this was his downfall. His physics teacher gave Jason a B, a mark Jason believed wouldundermine his entrance to Harvard. After receiving his B, Jason took a butcher knife to school and stabbed his physics teacher. How can someone as smart as Jason do something so dumb? Studies show there is little or no correlation between IQ and emotional intelligence. During my early university years, I regarded myself as an intelligent guy. I got good marks in mathematics, physics, and other subjects. I thought such skills would surely give me a bright future. After one year of study with decent marks, I began to see two major classes of students. The first category of students turned up to few lectures, partied every weekend, enjoyed a great social life, and did minimal work to pass courses. The second category of students were intelligent and hard workers who got good grades and were very focused on their studies. Surely would these intelligent and hard-working students find the great jobs before the other lazier class of students? Not so. Students are often shocked upon graduation that their qualifications are not as important as they once thought. Graduates enter the workforce only to realize that co-workers hate them and less intelligent people are the ones receiving promotions. Educational skills are useless in some industries when interpersonal skills are absent. You can have great ideas, theories, and solve complex problems, but if you cannot effectively communicate in a persuasive and exciting manner by relating to your fellow humans, you will face an uphill battle in whatever challenges you encounter. It's not that people dislike you because of your intelligence; it's that people dislike you because you're rude and not understanding. The intelligent person with poor communication skills is insensitive or unaware of others' emotions.
Answer: he got a worse mark than usual
[A]: Jason Haffizulla stabbed his physics teacher because _ .

[Q]: Article: A new research has uncovered that culture is a determining factor when people interpret facial emotions .The study reveals that in cultures where emotional control is the standard,such as Japan,the focus is placed on the eyes to interpret emotions. Whereas in cultures where emotion is openly expressed,such as the United States,the focus is on the mouth to interpret emotions. "These findings go against the popular theory that the facial expressions of basic emotions can be universally recognized," said University of Alberta researcher Dr.Takahiko Masuda." A person's culture plays a very strong role in determining how he will read emotions and needs to be considered when interpreting the facial expressions." These cultural differences are even noticeable in computer emoticons ,which are used to convey a writer's emotions by email and text message. The Japanese emotions for happiness and sadness vary in terms of how the eyes are drawn ,while the American emotions vary with the direction of the mouth. In the United States the emoticons:)and:) show a happy face,whereas the emoticons:(and:(show a sad face. However,the Japanese tend to use the symbol ('') to indicate a happy face,and (;;) to indicate a sad face. "We think it is quite interesting and appropriate that culture tends to mask its emotions. The Japanese would focus on a person's eyes when detecting his or her emotions,as eyes tend to be quite subtle ,"said Masuda. "In the United States,where an open emotion is quite common,it makes sense to focus on the mouth,which is the most expressive feature on a person's face."
Answer: culture is a key to interpreting facial emotions
[A]: The text mainly tells us that _ .

[Q]: Article: When a handheld video game runs out of power,all you have to do is plug it in and charge it up.Within a few years,some of you might do the same thing with mom's car.Automobile companies are developing vehicles that will plugin to electric sockets ,just like many laptops,digital cameras,cellphones and small video game players do.Called "plugin hybrids ",these cars will get most of their power from electricity.Their drivers will rarely have to stop at gas stations. The technology is more than just cool.In our automobilefilled world,plugin vehicles could reduce the amount of gasoline we use.That gas is made from crude oil ,which keeps rising in cost.Plus,driving around in these hybrids may even help the environment.Gasburning cars produce a lot of carbon dioxide,a type of greenhouse gas.These gases stay in the atmosphere,where they trap heat and cause global warming. The first companyproduced plugin hybrids could hit the roads by 2010.But engineers still have a lot of work to do to make the technology practical and inexpensive. Batteries are the biggest challenge.In the pluginhybrid world,lithiumion (Liion) batteries are getting the most attention.These batteries can store a large amount of energy in a small package,and they last a ly long time between charges.Liion batteries are standard in laptops,cellphones,heart devices and other similar portable devices. But because cars are so big and heavy,it would still require a suitcasesized Liion battery to power about 12km of driving.What's more,the batteries are extremely expensive. "A car filled with batteries could go a long distance," says Ted Bohn,an electrical engineer in Chicago."But it couldn't haul any people,and it would cost $100,000." So researchers need to figure out how to make batteries smaller and cheaper,among other questions. "The answers don't exist yet," Bohn says."As a kid I thought someone someplace knows the answer to everything.All of these questions haven't been decided.That's what engineering is about--making a guess,running tests and finetuning results."
