Question 1 of 5
1. Question
A box contains 4 black balls, 6 red balls and 8 blue balls. 3 balls are randomly drawn from the box. What is the probability that the balls are different?
Correct
Solution (b)
Let us assume that all balls are unique.
There are a total of 18 balls.
Total ways = 3 balls can be chosen in 18C3 ways = 816
Favourable ways = 1 black ball, 1 red ball, and 1 blue ball = 4 × 6 × 8 = 192
Probability = 192/816 = 4/17

Question 2 of 5
2. Question
Read the following three passages and answer the items that follow. Your answer to these items should be based on the passages only
During the 1960’s and 1970’s, the primary economic development strategy of local governments in the United States was to attract manufacturing industries. Unfortunately, this strategy was usually implemented at another community’s expense: many manufacturing facilities were lured away from their moorings elsewhere through tax incentives and slick promotional efforts. Through the transfer of jobs and related revenues that resulted from this practice, one town’s triumph could become another town’s tragedy.
In the 1980’s the strategy shifted from this zero-sum game to one called “high-technology development,” in which local governments competed to attract newly formed high-technology manufacturing firms. Although this approach was preferable to victimizing other geographical areas by taking their jobs, it also had its shortcomings: high-tech manufacturing firms employ only a specially trained fraction of the manufacturing workforce, and there simply are not enough high-tech firms to satisfy all geographic areas.
Recently, local governments have increasingly come to recognize the advantages of yet a third strategy: the promotion of home grown small businesses. Small indigenous businesses are created by a nearly ubiquitous resource, local entrepreneurs. With roots in their communities, these individuals are less likely to be enticed away by incentives offered by another community. Indigenous industry and talent are kept at home, creating an environment that both provides jobs and fosters further entrepreneurship.
The passage suggests which of the following about the majority of United States manufacturing industries before the high-technology development era of the 1980’s?
Correct
Solution (c)
“During the 1960’s and 1970’s, the primary economic development strategy of local governments in the United States was to attract manufacturing industries “. This line makes it clear that manufacturing industries could provide real economic benefits to the areas in which they were located.
Hence option c is the correct answer.

The author of the passage mentions which of the following as an advantage of high-technology development?
Correct
Solution (d)
“Unfortunately, this strategy was usually implemented at another community’s expense: many manufacturing facilities were lured away from their moorings elsewhere through tax incentives and slick promotional efforts……. In the 1980’s the strategy shifted from this zero-sum game to one called “high-technology development,” in which local governments competed to attract newly formed high-technology manufacturing firms.”
From this we can infer that option d is correct.

Question 4 of 5
4. Question
Researchers compared the number of tooth fractures in present-day carnivores with tooth fractures in carnivores that lived 36,000 to 10,000 years ago and that were preserved in the Rancho La Brea tar pits in Los Angeles. The breakage frequencies in the extinct species were strikingly higher than those in the present-day species.
In considering possible explanations for this finding, the researchers dismissed demographic bias because older individuals were not overrepresented in the fossil samples. They rejected preservational bias because a total absence of breakage in two extinct species demonstrated that the fractures were not the result of abrasion within the pits. They ruled out local bias because breakage data obtained from other Pleistocene sites were similar to the La Brea data. The explanation they consider most plausible is behavioural differences between extinct and present-day carnivores—in particular, more contact between the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct species. Such thorough carcass consumption implies to the researchers either that prey availability was low, at least seasonally, or that there was intense competition over kills and a high rate of carcass theft due to relatively high predator densities.
The passage suggests that, compared with Pleistocene carnivores in other areas, Pleistocene carnivores in the La Brea area
Correct
Solution (b)
“They ruled out local bias because breakage data obtained from other Pleistocene sites were similar to the La Brea data”.
This line makes it clear that option b is the correct answer.
Incorrect
Solution (b)
“They ruled out local bias because breakage data obtained from other Pleistocene sites were similar to the La Brea data”.
This line makes it clear that option b is the correct answer.

According to the passage, the researchers believes that the high frequency of tooth breakage in carnivores found at La Brea was caused primarily by
