Input: Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.
"Do electrons have a positive or negative charge?" is "Yes"?

OPTIONS:
- no
- yes
Output: no

Input: Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but Bin Laden considered the basic idea feasible. Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM, Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets. Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings, Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh").

Does the response "Get pilot training" correctly answer the question "What did Mihdhar and Hazmi obtain after the suicide of Azzam?"?

"The impact of her interest and work on the provision of legal services in the state of California is immeasurable," said Patricia Philips, senior of-counsel for Los Angeles' Morrison & Foerster. "Its value is felt every day by someone who would otherwise be floundering around in the legal system yet dealing with very serious problems." Zelon's public-interest work has not gone unnoticed. Several organizations that share her commitment to public service - including the National Legal Aid & Defender Association and the State Bar of California - have honored her. Two years ago, Zelon received the Laurie D. Zelon Pro Bono Award, which had been named for her one year earlier by the Law Firm Pro Bono Project, which she'd helped found. "I didn't find out until I was standing in the great hall of the Supreme Court, surrounded by 300 people who were there, that the award had been named for me and was thereafter going to be given in my name. It's very hard to believe, for anyone who knows me well, but I was actually speechless for a period," Zelon said. Zelon faced one of the greatest challenges of her legal career, she said, when her appointment to the bench forced her to switch gears from civil litigation to criminal law. "It was a steep learning curve for me," she said. "It's a whole different set of processes. The rules are different. The case law is a whole body unto itself." Attorneys praise Zelon for her thorough understanding of the law. "She's extremely well-versed in the law," Leon said. "She's very thorough in her research," Wong said. Of course, not all attorneys concur with every decision Zelon makes in court. Some city attorneys disagree with her interpretation of evidentiary statutes when Zelon puts limits on their use of hearsay testimony. But lawyers who have appeared before her say that they appreciate her intelligent interpretation of the law.

Question: "Name two attorneys who praised Zelon?"

OPTIONS:
- no
- yes

Answer: "Morrison and Wong"

Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate.

Question: "What does the fact that fossils have been found on the top of Mt. Everest?"

Response: "The fossils have been carried up there"
