Article: Many people have wondered what makes the oceans rise and fall on the word's beaches twice a day. Those tides are caused by the force of the Moon's gravity and the rotation of the Earth. Gravity acts on the center of any solid object. The Earth is mostly molten rock, but compared to the oceans, we can think of it as a solid object. As you know, the oceans are fluid and lie on the surface of the Earth. When the Moon is overhead, the oceans are four thousand miles closer to the Moon than the Earth's center is. Because the oceans are closer, the Moon pulls harder on the water than on the Earth. This stronger pull makes the water bunch up a little under the Moon, creating a high tide. At the same time, the oceans on the opposite side of the Earth are four thousand miles farther from the Moon than the Earth's center is. The Moon's pull on this water is weak. This water bunches up because it is "left behind"(making another high tide) as the Earth is pulled slightly towards the Moon. When the waters bunch up on these two sides of the Earth, they draw water away from the other sides of the Earth, which creates the low tides. As the Earth rotates, different parts of the land and oceans pass through the high-tide and low-tide zones. And that makes the waters on our coasts go up and down.
Answer: Moon's gravity or Earth rotation
answer:
According to the passage, there would be no tides if there were no _ .

Article: After years of hearing drivers complain about scratches on their cars, Japan's Nissan Motor Company has officially announced the next big thing--a paint that not only resists scratches and scrapes, but actually repairs itself within a few days. The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris or even on-purpose destruction. The automaker admits its results vary depending on the temperature and the depth of the damage, but adds "this is the only paint like it in the world, and tests prove it works." Minor scratches, the most common type, are said to slowly fade over about a week. And once they're gone, there is no trace that they were ever there. The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period. Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents. But the complete auto-healing won't come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 US to the price of a car. It plans to use its new chemical mixture only on its _ in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores as well.

answer:
From the article, we can find that _ .
