input: OPTIONS:
- A black hole can be very tiny but extremely heavy.
- The gravity of a black hole holds all light in its center.
- Scientists observe high-energy light through their own eyes.
- Some small black holes came into being as early as the universe. Now, answer this question: Read the following article and answer the question. Article: A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones. Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "staff", in an object. Another kind of black hole is called "stellar" . Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way. The largest black holes are called "supermassive" . These black holes have masses that are more than one million suns together. Scientists have found proof that every large _ contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths. Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in. A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole. When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human... Question: According to the passage, which of the following is NOT true? Answer:
A:
output: Scientists observe high-energy light through their own eyes.

- He was very disappointed.
- He was very angry.
- He was excited.
- He was quite depressed. Now, answer this question: Read the following article and answer the question. Article: Neil Armstrong, the first man to walk on the moon, has died at the age of 82. Many people paid tribute to the former astronaut. But other people feel regret that no human has been back to the moon since 1972, just three years after Armstrong landed on it and gave his famous "giant leap for mankind" speech. Elliot Pulham, Chief Executive of the Space Foundation, thinks that America's space agency NASA should get more money, like in the 1960s, during the moon landings programme, when astronauts went to the moon. "In this age of limited goals and tiny NASA budgets, Armstrong is a reminder of what our nation was once capable of," he said. Armstrong died because of heart problems after surgery. His recovery seemed to be going well, and his death was a surprise to many people. His family described him as a "reluctant American hero" and said: "Honour his example of service, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink." Speaking from the White House, Barack Obama said Armstrong was "among the greatest of American heroes - not just of his time, but of all time". He added: "And when Neil stepped on the moon for the first time, it was a moment of human achievement that will never be forgotten." Buzz Aldrin flew with Armstrong on Apollo 11. He was the second man to walk on the moon. He said he was very sad at the death of his good friend and companion. "When I look at the moon I remember that special moment, over forty years ago, when Neil and I stood on the moon," he said. "Looking back at our brilliant blue planet Earth hanging in the darkness of space, I realized that even though we were farther away from Earth than two humans had ever been, we were not alone. Almost the entire world took that memorable journey with us. I know many millions of people around the world will join me in mourning the death of a true American hero and the best pilot I ever knew. My friend Neil took the small step but giant leap that changed the... Question: What did Neil Armstrong almost certainly think of the current situation at NASA? Answer:
A:
output: He was very disappointed.

input: OPTIONS:
- The US has got most of its electricity from clean energy.
- US oil production is too small to keep the present low fuel prices.
- The US produced the most oil in 2010 in its history.
- The Gulf is still important in energy supply in spite of the oil spill in 2010. Now, answer this question: Read the following article and answer the question. Article: The US will seek to expand its own oil production in an attempt to reduce dependence on imported oil and bring down fuel prices , President Obama says . New contracts for exploration will be signed in non-protected areas of Alaska and in the Gulf of Mexico. In his weekly speech , the President insisted the US could reduce its need for imported oil and improve safety. Using his speech to tell Americans that he understood their concerns about rising prices, President Obama focused particularly on the price of fuel, which has risen in recent months. US consumers have historically enjoyed cheap fuel , but have seen prices rise in recent months even though US oil production in 2010 reached its highest level for seven years. Although the oil spill in the Gulf of Mexico in 2010 was serious, Mr Obama said the Gulf remained a key part of the country's future energy supply. The President's proposals come after Republicans introduced a series of proposals that would expand and speed up oil and gas production. The White House has criticized the Republican proposals for safety reasons , but Mr Obama was clear in his speech that he felt safety and environmental standards could be maintained even though production might rise. " I believe that we should continue to expand oil production in America --even as we increase safety and environmental standards ,"he said. "As a nation, we should be investing in the clean, renewable sources of energy that are the solution to high gas prices." Mr Obama has previously called for a step-change in energy policy, saying the US must move towards getting 80%of its electricity from clean energy sources by 2035. Question: What can we learn from the text ? Answer:
A:
output:
The Gulf is still important in energy supply in spite of the oil spill in 2010.
