In October 1933 Einstein returned to the U.S. and took up a position at the Institute for Advanced Study (in Princeton, New Jersey), noted for having become a refuge for scientists fleeing Nazi Germany. At the time, most American universities, including Harvard, Princeton and Yale, had minimal or no Jewish faculty or students, as a result of their Jewish quota which lasted until the late 1940s. Einstein was still undecided on his future. He had offers from several European universities, including Oxford where he stayed for three short periods between May 1931 and June 1933, however in 1935 he arrived at the decision to remain permanently in the United States and apply for citizenship. Einstein's affiliation with the Institute for Advanced Study would last until his death in 1955. He was one of the four first selected (two of the others being John von Neumann and Kurt Godel) at the new Institute, where he soon developed a close friendship with Godel. The two would take long walks together discussing their work. Bruria Kaufman, his assistant, later became a physicist. During this period, Einstein tried to develop a unified field theory and to refute the accepted interpretation of quantum physics, both unsuccessfully.

Question: "How many years was Einstein affiliated with the Institute for Advanced Study?"

Answer: "2 years"

Response: no

Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.

Question: "What leads to decrease in size of chest while exhaling"

Answer: "Increase in air pressure"

Response: yes

Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.

Question: "How are electrical charges similar to a teeter-totter?"

Answer: "You'll get shocked if you touch a teeter-totter"

Response: no

Mary loved walking through the woods with her dog, Max. Max and Mary would go on all sorts of adventures together. They really loved looking for blueberries together and then falling asleep next to each other in the tall grass. One day, as Mary was picking the blueberries, she turned around to find that Max was not there. She became worried and ran off to look for her dog. She looked in all of their favorite spots...next to the stream, in their secret hiding place behind the raspberry bushes, and even inside the old cabin that sat in the woods. But poor Max was nowhere to be found. Nonetheless, Mary would not give up. She kept looking and she found him not very far away. He had seen a squirrel and run to chase it. When Mary called Max's name he left the squirrel and happily returned to Mary, wagging his tail as he went.

Question: "What things did Mary do?"

Answer: "She went to look for blueberries and she went in search of her dog"

Response:
yes
