The correct answer is B - It describes the new inhabitants of the village.

The second paragraph describes the village following the departure of its human inhabitants. It does not outline the reasons for the relocation of the former inhabitant (this is given in the second paragraph), nor does it compare different types of animals or talk about regeneration of the land. Paragraph 3 merely describes the new village inhabitants - animals. Therefore, answer choice B is correct.

The correct answer is A - The weather is rainy in high altitudes.

The third paragraph presents the following logic: If you are heading to higher elevations then invest in warm bags that dry out quickly when they get wet. The missing assumption here is that in higher altitudes there is rain (and colder weather) and that is why you need a sleeping bag that dries out quickly. If that is not the case, there would be no reason to buy a sleeping bag that dries out quickly. Therefore answer A is correct.

The correct answer is B - He ran a marathon.

In order to conclude which of the statements is definitely true, we must locate them in the text and find which one of them is explicitly mentioned there. In this case, it is easy to locate the section in the text corresponding to the answer choices, as the question provides us with a clue (”Jack Foster”) leading us to our answer. This is the section that refers to Foster:” One example is the great Jack Foster, a self-styled "ancient marathoner”, who ran for the first time at the age of 32, and by the age of 40 found himself picking up a silver medal at the Christchurch Commonwealth marathon in 1974”.

It is said that Foster: (1) ran for the first time at the age of 32 – this eliminates answer choice (a). (2) ran a marathon in Christchurch – however, we do not know if he actually lived there, thus eliminating answer choice (c). (3) he is a self-styled ”ancient marathonist”- which does not mean he is stylish, eliminating answer choice (d). Since the text states explicitly that Foster ran a marathon, answer choice (b) is thus the correct answer.

Answer B is incorrect because it says that David has been working, but doesn't specify that he was working at University High School for seven years.

Answer C is incorrect because it says that David was 35 years old for seven years.

Answer D is incorrect because it is vague. is David now 35 after working for seven years, or was he 35 years old before doing so?

The correct answer is D.

Answer D says the quality of the toothpaste is also important, which was not mentioned originally.

The correct answer is B - The extensive tissue damage caused by third-degree burns guarantees scarring.

Answer choice A is incorrect. This is the description of first-degree burns.
Answer choice C is incorrect. Third-degree burns don't cause pain due to the extensive damage to the nerves. It is second-degree full thickness burns that are described as very painful.
Answer choice D is incorrect. This is true only for first-degree burns. Third-degree burns take months to heal.

The correct answer is (D).
Some of Georgia's service industry employees drink Coke.

The key to solving this problem is to figure out the sums (percentages) for each statement. If the results are greater than 100%, we can identify an overlap between categories.
Answer (A) - Half of Georgia’s coke-drinking inhabitants are Native Americans. If 60% of inhabitants drink Coke, then the Native American inhabitants that drink Coke make up 30% of Georgia's total population. And 30% of Georgia's inhabitants are Native Americans, so the sum of the two groups is 60% (i.e. 30% + 30%= 60% < 100%) of the population. There isn't a definite overlap between the categories.
Answer (B) - One-third of Georgia's coke-drinking inhabitants is 20% (1/3*60) and 20% of Georgia's inhabitants work in agriculture (i.e. 20% + 20%= 40% < 100%). However, there is no indication of overlap between the two groups.
Answer (C) - Whether there is an overlap between Georgia's Native American inhabitants and the service industry and agriculture workers is unknown, as Georgia's Native American inhabitants constitute 30% of Georgia's population, and service industry and agriculture workers together constitute 70% of Georgia's population (i.e. 30% + 70%= 100%). Also, even if Native Americans are divided between working in the service industry and in agriculture, there is no way of knowing how they are divided among those jobs.
Answer (D) - According to the data provided, service industry workers constitute 50% of Georgia's population. Furthermore, cola drinkers constitute 60% of Georgia's population. This means there is a definite overlap between service industry workers and cola drinkers (i.e. 50% + 60%= 110% > 100%). Therefore, some of Georgia's service industry employees definitely drink Coke (at least 10% of them).
Answer (E) - Two extreme possibilities must be taken into consideration while testing the statement's validity:
1. There is no overlap between the agriculture workers and the coke drinkers - in that case they constitute 80% of Georgia's population, which means those who are neither agriculture workers nor coke drinkers constitute 20% of Georgia's population. One fifth of those 20% equals 4% which are claimed to be the percentage of Native Americans in Georgia's population. However, it is known that 30% of Georgia's population is Native American. Therefore, this option is invalid.
2. There is a full overlap between agriculture workers and coke drinkers - in that case they constitute 60% of Georgia's population, which means those who are neither agriculture workers nor coke drinkers constitute 40% of Georgia's population. One fifth of those 40% equals 8% which are claimed to be the percentage of Native Americans out of Georgia's population. However, it is known that 30% of Georgia's population is Native American. Therefore, this option is invalid.

The correct answer is C.

Remember that for questions of the type Identifying an Underlying Assumption of the argument, the correct answer will not appear in the passage. It is something that must be assumed to be true in order for the argument to be true. The argument in this passage is clearly the last sentence, beginning with the signal word Therefore: Therefore, when the supercomputers are completed, there will be a shortage of people who know how to make use of all this computing power. Before reading the answer choices, you know that you are looking for a sentence that will support the fact that there will be a shortage of sufficiently trained people. It can be found in answer choice C: An insufficient number of people are being trained now to run the supercomputers when completed. Therefore, the correct answer is C.
