input: Please answer the following: I can use this background: A comet tailand comaare features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. Separate tails are formed of dust and gases, becoming visible through different phenomena; the dust reflects sunlight directly and the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye. Now, I have a new situation: Year 2022 would be an interesting year when three comets would get scientists' attention - Comet A, Comet B, and Comet C. Comet A and C are very faint, but Comet B is very bright. Comet A would enter the inner solar system on February 10, 2022 and leave the inner solar system on February 20, 2022. Comet B would enter the inner solar system on February 18, 2022 and leave the inner solar system on February 26, 2022. Comet C would never enter the inner solar system. Answer this question please: Would Comet B be visible or not visible on February 28, 2022?

output: not visible
Please answer this: I can use this background: Soon after the original study was published, other researchers tried to replicate the research. However, it could not be replicated. No other studies could find a link between the vaccine and autism. As a result, scientists became convinced that the original results were incorrect. Eventually, investigators determined that the original study was a fraud. They learned that its author had received a large amount of money to find evidence that the vaccine causes autism, so he faked his research results. If other scientists had not tried to replicate the research, the truth might never have come out. You can read more about this case at the URL below. Now, I have a new situation: John works for the NSF. He has two research proposals in front of him, case A and case B. Both are looking for further funding. Case A research has been replicated by other researchers, but case B research could not be replicated by others. He needs to decide which research should get further funding. Answer this question please: For which reasearch John should not offer funding, case A or case B?
++++++++
Answer: case B
Problem: I can use this background: Hypertension , which is also called "high blood pressure," occurs when a person's blood pressure is always high. Hypertension is said to be present when a person's systolic blood pressure is always 140 or higher, and/or if the person's diastolic blood pressure is always 90 or higher. Having hypertension increases a person's chance for developing heart disease, having a stroke, or suffering from other serious cardiovascular diseases. Hypertension often does not have any symptoms, so a person may not know that he or she has high blood pressure. For this reason, hypertension is often called the "silent killer." Treatments for hypertension include diet changes, exercise, and medication. Foods thought to lower blood pressure include skim milk, spinach, beans, bananas and dark chocolate. Now, I have a new situation: Jeremy went to the doctor for his yearly physical along with his wife Brenda. The doctor told Jeremy that his blood pressure was consistently high. Brenda, on the other hand, was told that her blood pressure was in the normal range. Aside from this difference, the overall health of Jeremy and Brenda was similar. Answer this question please: Who has a lower risk of having a stroke?

A: Brenda
Problem: Given the question: I can use this background: Many respiratory diseases are caused by pathogens. A pathogen is an organism that causes disease in another organism. Certain bacteria, viruses, and fungi are pathogens of the respiratory system. The common cold and flu are caused by viruses. The influenza virus that causes the flu is pictured below ( Figure below ). Tuberculosis, whooping cough, and acute bronchitis are caused by bacteria. The pathogens that cause colds, flu, and TB can be passed from person to person by coughing, sneezing, and spitting. Illnesses caused by bacteria can be treated with antibiotics. Those caused by viruses cannot. Now, I have a new situation: People of Iran had more respiratory diseases caused by fungi and viruses, while their neighbor Iraq had more disease caused by bacteria. Answer this question please: Which country had fewer people with the flu?
++++++++++++++++++++++++++++++++
The answer is:
Iraq
input question: I can use this background: Alpine tundra occurs at high enough altitude at any latitude. Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, and the Eastern Rift mountains of Africa.Alpine tundra occupies high-mountain summits, slopes, and ridges above timberline. Aspect plays a role as well; the treeline often occurs at higher elevations on warmer equator-facing slopes. Because the alpine zone is present only on mountains, much of the landscape is rugged and broken, with rocky, snowcapped peaks, cliffs, and talus slopes, but also contains areas of gently rolling to almost flat topography.Averaging over many locations and local microclimates, the treeline rises 75 metres (245 ft) when moving 1 degree south from 70 to 50N, and 130 metres (430 ft) per degree from 50 to 30N. Between 30N and 20S, the treeline is roughly constant, between 3,500 and 4,000 metres (11,500 and 13,100 ft). Now, I have a new situation: Redland and Brownland were two countries situated at different latitudes. Redland was located at 70 degrees N, while Brownland was much further south, at 30 degrees N. Brownland had no mountains, only a few hills under 1000 ft. Answer this question please: Which country had less alpine tundra????
output answer: Brownland
input question: I can use this background: Acromyrmex heyeri is a species of leaf-cutter ant, a New World ant of the subfamily Myrmicinae of the genus Acromyrmex. Acromyrmex heyeri workers construct the colonies nest by thatching together cut grass. At temperatures ranging from 2030 C, workers created more openings in the nest thatch as the internal nest temperature goes up as a method of temperature regulation for the colony. The workers will close openings in the nest thatch as the air humidity surrounding the nest decreases to reduce water loss for the colony. Now, I have a new situation: In the ant world a war has been waged. Two rival groups of Acromyrmex heyeri ants, group A and group B, are battling each other to gain territory. The goal is to attack the rival group when they have more openings in their nest thatch. In battle day one group A territory had 5 C temperature. In battle day two group A territory had 22 C temperature. In battle day three group A territory had low air humidity. In battle day four group A territory had high air humidity. Answer this question please: In battle day four would group A have less openings or more openings in their nest thatch????
output answer:
more openings
