Problem: Please answer a question about the following article about Daylight saving time:
DST's potential to save energy comes primarily from its effects on residential lighting, which consumes about 3.5% of electricity in the United States and Canada. Delaying the nominal time of sunset and sunrise reduces the use of artificial light in the evening and increases it in the morning. As Franklin's 1784 satire pointed out, lighting costs are reduced if the evening reduction outweighs the morning increase, as in high-latitude summer when most people wake up well after sunrise. An early goal of DST was to reduce evening usage of incandescent lighting, which used to be a primary use of electricity. Although energy conservation remains an important goal, energy usage patterns have greatly changed since then, and recent research is limited and reports contradictory results. Electricity use is greatly affected by geography, climate, and economics, making it hard to generalize from single studies.
DST will reduce electricity use in the evening but increase it during what time of the day?
A: morning
Problem: Please answer a question about the following article about On the Origin of Species:
His answer was that in many cases animals exist with intermediate structures that are functional. He presented flying squirrels, and flying lemurs as examples of how bats might have evolved from non-flying ancestors. He discussed various simple eyes found in invertebrates, starting with nothing more than an optic nerve coated with pigment, as examples of how the vertebrate eye could have evolved. Darwin concludes: "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find out no such case."
How did Darwin justify his theory not breaking down?
A: any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.
Problem: Please answer a question about the following article about Middle Ages:
One of the major developments in the military sphere during the Late Middle Ages was the increased use of infantry and light cavalry. The English also employed longbowmen, but other countries were unable to create similar forces with the same success. Armour continued to advance, spurred by the increasing power of crossbows, and plate armour was developed to protect soldiers from crossbows as well as the hand-held guns that were developed. Pole arms reached new prominence with the development of the Flemish and Swiss infantry armed with pikes and other long spears.
What troops were uniquely successful in English service?
A: longbowmen
Problem: Please answer a question about the following article about Botany:
Inheritance in plants follows the same fundamental principles of genetics as in other multicellular organisms. Gregor Mendel discovered the genetic laws of inheritance by studying inherited traits such as shape in Pisum sativum (peas). What Mendel learned from studying plants has had far reaching benefits outside of botany. Similarly, "jumping genes" were discovered by Barbara McClintock while she was studying maize. Nevertheless, there are some distinctive genetic differences between plants and other organisms.
What other plant was used in the discovery of different genes?
A:
maize
