Direction: The logic problems in this set present you with three true statements : Fact 1, Fact 2, and Fact 3. Then, you are given three more statements (labeled I, II, and III), and you must determine which of these, if any, is also a fact. One or two of the statements could be true; all of the statements could be true; or none of the statements could be true. Choose your answer based solely on the information given in the first three facts.
-
Fact 1 : Islands are surrounded by water.
Fact 2 : Maui is an island.
Fact 3 : Maui was formed by a volcano.
If the first three statements are facts, which of the following statements must also be a fact?
I. Maui is surrounded by water.
II. All islands are formed by volcanoes.
III. All volcanoes are on islands.
-
- I only
- III only
- I and II only
- None of the statements is a known fact.
Correct Option: A
Since Maui is an island and islands are surrounded by water, Maui must be surrounded by water. There is not enough information to support statements II and III.
