Question:
Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar. After reading the above, is "It takes a lot of energy to make it" the correct answer to the question "What is risky for a plant with its nectar?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Hamilton argued that the natural faculties of blacks were as good as those of free whites, and he warned that the British would arm the slaves if the patriots did not. In his 21st-century biography, Chernow cites this incident as evidence that Hamilton and Laurens saw the Revolution and the struggle against slavery as inseparable. Hamilton attacked his political opponents as demanding freedom for themselves and refusing to allow it to blacks. In January 1785, Hamilton attended the second meeting of the New York Manumission Society (NYMS). John Jay was president and Hamilton was the first secretary and later became president. Chernow notes how the membership soon included many of Hamilton's friends and associates. Hamilton was a member of the committee of the society that petitioned the legislature to end the slave trade, and that succeeded in passing legislation banning the export of slaves from New York. In the same period, Hamilton felt bound by the rule of law of the time and his law practice facilitated the return of a fugitive slave to Henry Laurens of South Carolina. He opposed the compromise at the 1787 Constitutional Convention by which the federal government could not abolish the slave trade for 20 years, and was disappointed when he lost that argument. Hamilton never supported forced emigration for freed slaves. Horton has argued from this that he would be comfortable with a multiracial society, and that this distinguished him from his contemporaries. In international affairs, he supported Toussaint L'Ouverture's black government in Haiti after the revolt that overthrew French control, as he had supported aid to the slaveowners in 1791--both measures hurt France. Scant evidence has been interpreted by a few to indicate Hamilton may have owned household slaves, as did many wealthy New Yorkers (the evidence for this is indirect; McDonald interprets it as referring to paid employees).
"How did Hamilton feel about black people?" is "Hamilton believed black people had faculties equal to white people and saw the struggle of black people as inseparable from the Revolution"?

Input: Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate.

Does the response "Stayed the same" correctly answer the question "Did Antarctica's climate change throughout history?"?

OPTIONS:
- no
- yes

Output: no

Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "What does density tell?"

OPTIONS:
- no
- yes

Answer: "How closely packed the particles of matter are"

Response: yes
