Archaeologists have excavated two ancient sites, Site A and Site B, each containing bowls and dishes. A third site containing similar vessels (bowls and dishes), Site C, Is known to have existed but has not yet been located. The vessels have been dated to three successive 40-vear-long time periods (Mil).

The dishes that were found are small and plain and were made primarily for everyday use. For each site, the average population at the site for a period is known to be roughly proportional to the number of dishes found that were dated to that period.

The bowls are more elaborate, decorated In either a curvy or a rectilinear style. They were made primarily for ritual use. The numbers of bowls found indicate the level of wealth of the site ' s inhabitants during the period to which the bowls were dated (with greater numbers indicating greater wealth).

Documents found at Sites A and B establish that exactly 18 of the dishes found at Site A were manufactured at Site C; otherwise, all of the vessels were made at the sites where they were found.

For each of Sites A through C, select Yes If the Information provided Indicates that the population at that site was both greater in Period II than Period I and greater in Period III than in Period II. Otherwise, select No.

The artist has correctly determined that to make the largest possible square grid from the available tiles, she must use all of the except for those in the group of X tiles. Moreover, if she uses all of the tiles except for those in the group with X tiles and those in the group with Y tiles, she could make a smaller square grid.

select for X for Y the values that are consistent with the information provided. Make only two selections, one in each column.

Which one of the following is the total number of bowls found at Site B that have no Identified artisan?

Two positive integers, A and B, each yield the same remainder when divided by 4. Furthermore, A is less than IS. In the table, select values for A and 5that are jointly consistent with the given information. Make only two selections, one in each column.

In only a very few of the cases where plants have been said to be engaged in " chemical warfare, " such as In the case of knapweed and certain shrubs In California chaparral country, there Is solid evidence that secreted toxins are the inhibitory growth factor acting against neighboring plants.

I It is said of parasitic forms of life that, although they burden their hosts, they do not kill them, since a parasite cannot survive unless its host does. Mr. Craig ' s prize-winning lilies, however, were invaded by dodder, a parasitic plant, and every one of the lilies died soon after. Plainly, therefore, a parasite can be deadly.

The argument above depends on which of the following assumptions?

(1) x is an even integer. (2)* Is greater than 0.
