Question 1
Speaker: The coastal area of Melos, Greece, was a natural source for obsidian, which was highly sought after as material for making many stone implements during the Neolithic Age and the Bronze Age. A study by archaeologists examining stone implements from Neolithic and Bronze Age sites in Greece shows that, of those implements, the percentage made of obsidian varies with those sites' distance from Melos. For sites within 150 kilometers (km), the percentage is 85-100 percent; for those between 150 and 200 km, the percentage is 40-70 percent; and for those greater than 200 km away, the percentage is less than 30 percent. This variation is due to differential access to water-borne transportation. Select for Implies is true the statement that the speaker’s argument most clearly implies is true, and select for Implies is false the statement that the speaker's argument most dearly implies is false. Make only two selections, one in each column.
Question 2
At the annual holiday party of a particular company, each person is given a choice of 5 opportunities to win a prize. Specifically, each employee writes his/her name on a piece of paper and places it into one of 5 boxes, with each box representing a particular prize. One name is drawn from each box at random, and the 5 individuals thus named win the respective prizes. Gertrude is the last person to arrive at the holiday party and to place her name in one of the boxes. She knows, for each of the boxes, the number of individuals who have already placed their names in the box. And she knows the cash value of each of the prizes, in US dollars. This information is reflected in the graph. Select from the drop-down menus the options that create the most accurate statement about the expected outcomes (the cash value of the prize corresponding to the chosen box multiplied by the probability of winning) of Gertrude's possible choices.
