  1. Using the database you were assigned and the following simple statements search for (parenthesis required).
    • d = death penalty
    • c = capital punishment
    • n =New York
      State
      Search for:

      1. n /\ ( d \/ c )  (1470) hits
      2. ( n /\ d ) \/ c  (2155 ) hits
      3. n /\ d \/ c  (1470) hits
      4. ( n /\ d) \/ ( n /\ c) (687) hits

2) In part 1, which searches yield the same results and why?

In part one, the searches that yield the same results is A and C, because they both are searching for the same result of death or capital punishment and the search is the same except that the parenthesis makes the search look different when it is really the same search.

3) For each of the searches above, determine which Venn diagram corresponds to the search:

a) Search A corresponds with Venn diagram C, because it includes everything but excludes the A, and B search.

b) Search B corresponds with Venn diagram D, because it includes everything in A, B, and C.

c) Search C corresponds with Venn diagram D, again because it includes everything in A, B, and C, it is the same question. It is just placed in a different order.

D) Search D corresponds with Venn diagram C, because it is what is in N and D or what is in N and C.
