Fact 1:All drink mixes are beverages. Fact 2:All beverages are drinkable. Fact 3:Some beverages are red. If the first three statements are facts, which of the following statements must also be a fact? I:Some drink mixes are red. II:All beverages are drink mixes. III:All red drink mixes are drinkable.
Fact 1:All chickens are birds. Fact 2:Some chickens are hens. Fact 3:Female birds lay eggs. If the first three statements are facts, which of the following statements must also be a fact? I:All birds lay eggs. II:Some Hens are birds. III:Some chickens are not hens.
The first statement cannot be true because only female birds lay eggs. Statement II is true because some hens are chickens and all chickens are birds. Statement III is also true because if only some chickens are hens, then some must not be hens.
Fact 1:All hats have brims. Fact 2:There are black hats and blue hats. Fact 3:Baseball caps are hats. If the first three statements are facts, which of the following statements must also be a fact? I:All caps have brims. II:Some baseball caps are blue. III:Baseball caps have no brims.
All baseball caps have brims, since baseball caps are hats (Fact 3) and all hats have brims (Fact 1). This rules out statement III, but it doesn't follow that all caps, a category that may include caps that are not baseball caps, have brims (statement I). Statement II cannot be confirmed, either, since it is possible, given the information, that all baseball caps are black.
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.
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.
Fact 1:Robert has four vehicles. Fact 2:Two of the vehicles are red. Fact 3:One of the vehicles is a minivan. If the first three statements are facts, which of the following statements must also be a fact? I:Robert has a red minivan. II:Robert has three cars. III:Robert's favorite color is red.
There is not enough information to support any of the statements. Robert is known to have a minvan, but it is not known which of his vehicles is red. Robert may have a pickup or sport utility vehicle, so the second statement cannot be supported. There is no way to know if Robert's favorite color is red (statement III).
Fact 1:Eyeglass frames cost between $35 and $350. Fact 2:Some eyeglass frames are made of titanium. Fact 3:Some eyeglass frames are made of plastic. If the first three statements are facts, which of the following statements must also be a fact? I:Titanium eyeglass frames cost more than plastic frames. II:Expensive eyeglass frames last longer than cheap frames. III:Only a few eyeglass frames cost less than $35.
There is no information in the facts to support statements I or II. Statement III is clearly wrong because, according to Fact 1, no frames cost less than $35.
