Problem: Background: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume. Paragraph: Two islands were situated in different oceans. Hill island used fossil fuels and released a lot of carbon dioxide into the atmosphere, while Coral island was very protective towards the air and the ocean. Given the paragraph above, please answer correctly the following question: Which island contributed more to ocean acidification?

A: Hill

Problem: Background: East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended periods. Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded. Paragraph: Two scientists went to Antarctica for research. Tim was assigned to East Antarctica, while John was assigned to West Antarctica. They spent 6 months there. Given the paragraph above, please answer correctly the following question: Which scientist experienced more precipitation?

A: Tim

Problem: Background: They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed. Paragraph: Two frogs are being examined in a laboratory. Frog X was found in a pond in the forest and has a parasite in it. Frog Y was found just outside the laboratory and is missing one eye. The employees at the lab weren't planning on analyzing any frogs, but when they found the one outside their front door they changed their mind. Given the paragraph above, please answer correctly the following question: Which frog is in a symbiotic relationship?

A: Frog X

Problem: Background: Alpine climate is the average weather (climate) for the alpine tundra. The climate becomes colder at high elevationsthis characteristic is described by the lapse rate of air: air tends to get colder as it rises, since it expands. The dry adiabatic lapse rate is 10 C per km (5.5 F per 1000 ft) of elevation or altitude. Therefore, moving up 100 metres (330 ft) on a mountain is roughly equivalent to moving 80 kilometers (45 miles or 0.75 of latitude) towards the pole. This relationship is only approximate, however, since local factors such as proximity to oceans can drastically modify the climate. Paragraph: Two meteorologists study Earth's climate. Jerry studies alpine climate, while James studies tropical climates. They both made great progress. Given the paragraph above, please answer correctly the following question: Which person observed that the climate becomes colder at high elevations?

A:
Jerry
