Q: Passage: The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma consists of mostly electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV. Embedded within the solar-wind plasma is the interplanetary magnetic field. The solar wind varies in density, temperature and speed over time and over solar latitude and longitude. Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona, which in turn is a result of the coronal magnetic field.

Question: Based on this passage, what is made up of charged particles that continually escape from the corona?
A: The solar wind. How to explain the answer? The important part for answering this question is: The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona.

Q: Passage: The final draft of the Declaration was approved by the Continental Congress on July 4, although the date of its signing has long been disputed. Most historians have concluded that it was signed on August 2, 1776, nearly a month after its adoption, and not on July 4 as is commonly believed.

Question: Based on this passage, when did they sign the declaration of independence?
A: August 2 , 1776. How to explain the answer? To answer the above question, the relevant sentence is: Most historians have concluded that it was signed on August 2, 1776, nearly a month after its adoption, and not on July 4 as is commonly believed.

Q: The mucosa is the innermost layer of the gastrointestinal tract. It surrounds the lumen of the tract, and comes into direct contact with digested food (chyme). The mucosa itself is made up of three layers:

Based on this passage, which layer of the digestive tract is in direct contact with digested food?
A: mucosa. How to explain the answer? To answer the question, consider the following: It surrounds the lumen of the tract, and comes into direct contact with digested food (chyme).

Q: About 90 % of the world's earthquakes and 81 % of the world's largest earthquakes occur along the Ring of Fire. All but three of the world's 25 largest volcanic eruptions of the last 11,700 years occurred at volcanoes in the Ring of Fire. The Ring of Fire is a direct result of plate tectonics: the movement and collisions of lithospheric plates, especially subduction in the northern portion. The southern portion is more complex, with a number of smaller tectonic plates in collision with the Pacific plate from the Mariana Islands, the Philippines, Bougainville, Tonga, and New Zealand.

Hawaii is in the center of the ring of fire and is caused by?
A:
plate tectonics. How to explain the answer? The relevant sentence in the passage is: The Ring of Fire is a direct result of plate tectonics: the movement and collisions of lithospheric plates, especially subduction in the northern portion.
