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.
The right approach will be "Imaginary boundaries".
Explanation:
A boundary seems to be real as well as an imaginary line dividing two entities from each other. In geography, numerous parts of the World are divided by borders.
Mapped limits that always form a straight line become known as imaginary limits. These boundaries are often represented through points of border protection whereby entry from one direction toward the other remains regulated.
