On December 6, 2011, the National Aeronautical Space Administration (NASA) announced that scientists had discovered a "habitable
" planet, that is, a planet that is capable of sustaining life. The scientists named the planet Kepler-22b. It is more than twice the size of Earth. The
discovery of Kepler-22b came about as a result of NASA's Kepler mission, a group of scientists that searches for planets that could possibly sustain
life.
Like Earth, Keple:-22b orbits a star. Its star is similar to Earth's Sun. Kepler-22b's distance from its star is far enough away that the planet is
not extremely hot. Kepler-22b is also close enough to the star that the planet is not incredibly cold. The average surface temperature is believed to
be 72 °F (22 °C). Scientists say that Kepler-22b is within "The Goldilocks Zone." This means that it orbits at a distance from its star that allows its
temperature and other conditions to be "Just right" for supporting life.
There is much to learn about Kepler-22b. Scientists don't know what Kepler-22b is made of. They have not yet discovered if it is made mainly
of rocks, gases, or liquids. Exploration of Kepler-22b is unlikely to happen any time in the near future. It would take 22 million years to get there
because Kepler-22b is 600 light years away. Exploring Kepler-22b would be the greatest achievement in space science.
Which sentence about Kepler-22b is NOT supported by facts in the passage?
O 1. Kepler-22b's distance from its star is far enough away that the planet is not extremely hot.
2. There is much to learn about Kepler-22b.
3. Exploration of Kepler-22b is unlikely to happen any time in the near future.
O 4. Exploring Kepler-22b would be the greatest achlevement in space science.
An irrigation system represents a stable food supply because it is how they controlled water to be able to plant crops. A second most important artifact that is in the category of stable food supply is the plow. Agriculture produced enough food that people became free to pursue interests other than worrying about what they were going to eat that day.
When those firms which are already existance in market feels threat from new entarnts. Then, they try to discourage the new entarnts to maintain their position in market and to earn same profit margins.
The stock market crashing and the problems at the banks
Explanation:
I think the stock market crashing and the problems at the banks could’ve been the two biggest causes of the Great Depression because at the time money way a very important factor to just about everything and with money not being in order and with people losing their money after the stock market crash it caused major problems and the fact that some people couldn’t even get the money they had in the banks made it worst.
