Example Input: Article: Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle. Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practical sewing machine. Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing Jane Eyre. To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious ,but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called "secret messages to ourselves ".
Answer: the only person at the time who knew the value of dreams
Example Output: According to the passage,Elias Howe was _ .

Example Input: Article: An argument is appearing in Los Angeles over whether a newspaper should publish teachers' names along with an analysis of how well they do in raising their students' standardized test scores. Some people argue that transparency should exist at all costs, but others hold that it's unfair to label individual teachers using possibly flawed statistics. Some worry that anger over the forthcoming Los Angeles Timesarticle will make people oppose so-called "value added" analysis of teacher performance, which is the method the Times uses. "This incident with the L.A. Times is where the advocates for value-added are getting a bit ahead of themselves," says Douglas Harris, an education professor. " _ the gun on this kind of thing." "Value-added data" is the latest trend in teacher responsibility: the idea that a student's gain from the previous year's test -- as opposed to his or her overall performance -- can be measured and tied to the latest teacher. "There are too many variables in the testing process," says A.J. Duffy. But he says he opposes using value-added data in evaluations at all, although he acknowledges it could be a useful tool to give teachers feedback. "I believe in a system that emphasizes the whole student, not just standardized tests," he says. Proponents of value-added say that's a valid criticism, agreeing that no one should expect that student gains on a standardized test could capture the creativity or broader enrichment that goes on in many teachers' classrooms. The District of Columbia which attracted argument for its decision to fire teachers based in part on value-added data, uses that data for 50 percent of the evaluation, relying on other measures such as classroom observation for the rest. "No one is suggesting using _ as a single measure of performance," says Paige Kowalski. Barnett Berry, a professor, is even more critical of it. Value-added data can be useful, he and others say, but it's important to acknowledge its limitations. It doesn't take into account, for instance, constant student absence and learning gains due to summer school, after-school programs, or supplemental teachers, such as reading specialists.
Answer: the feedback of students and parents
Example Output: In the opinion of Mr. Duffy, teachers should be judged by _ .
