How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe.

Question: "How was the universe made?"

Response: "From food and water"
OPTIONS:
- no
- yes

A: no

Problem: Sometimes traits can vary from parent to offspring. These changes are due to mutations. Mutations are a random change. Mutations are natural. Some mutations are harmful. In this case, the organism may not live to reproduce. The trait will not be passed onto offspring. Others variations in traits have no effect on survival. Can some mutations be good for a living thing? Other mutations can have great benefits. Imagine being the first moth that can blend into its background. It would have a better chance of survival. A living thing that survives is likely to have offspring. If it does, it may pass the new trait on to its offspring. Thats good news for the offspring. The offspring may be more likely to survive. Mutations are one way living things adapt to new conditions.

Question: "What are mutations good for?"

Answer: "Mutations are good for a better chance of survival, and a way for living things to adapt to new conditions"

- no

Answer: yes

Question:
Physical properties include the state of matter. We know these states as solid, liquid, or gas. Properties can also include color and odor. For example, oxygen is a gas. It is a major part of the air we breathe. It is colorless and odorless. Chlorine is also a gas. In contrast to oxygen, chlorine is greenish in color. It has a strong, sharp odor. Have you ever smelled cleaning products used around your home? If so, you have probably smelled chlorine. Another place you might smell chlorine is at a public swimming pool. The chlorine is used to kill bacteria that may grow in the water. Other physical properties include hardness, freezing, and boiling points. Some substances have the ability to dissolve in other substances. Some substances cannot be dissolved. For example, salt easily dissolves in water. Oil does not dissolve in water. After reading the above, is "solid and gas" the correct answer to the question "Which of the mentioned physical states most likely lack the property of hardness?"? OPTIONS:
- no
- yes

Answer:
no

Input: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.
"How do garden warblers use the earth's magnetic field to guide animal migration?" is "Visual pattern"?

OPTIONS:
- no
- yes
Output: no

Input: These incoherent words threw the first glimpse of light on the meaning of her distress and penitence. I doubt if the best woman in Christendom would so reproach and abase herself, if convicted of even a worse sin than the secret use of those stimulants for which the "charny" is a Martial equivalent. No Martialist would dream of poisoning his blood and besotting his brain with alcohol in any form. But their opiates affect a race addicted to physical repose, to sensuous enjoyment rather than to sensual excitement, and to lucid intellectual contemplation, with a sense of serene delight as supremely delicious to their temperament as the dreamy illusions of haschisch to the Turk, the fierce frenzy of bhang to the Malay, or the wild excitement of brandy or Geneva to the races of Northern Europe. But as with the luxury of intoxication in Europe, so in Mars indulgence in these drugs, freely permitted to the one sex, is strictly forbidden by opinion and domestic rule to the other. A lady discovered in the use of "charny" is as deeply disgraced as an European matron detected in the secret enjoyment of spirits and cigars; and her lord and master takes care to render her sufficiently conscious of her fault.

Does the response "Bhang" correctly answer the question "What was the luxury intoxication of Europe?"?

OPTIONS:
- no
- yes

Output: yes

Input: Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.

Does the response "Electricity wire" correctly answer the question "What is on top of the poles on the roadside?"?

- no
- yes
