LLN Critical Thinking & Reasoning

Question 1

If all squares are rectangles and all rectangles are parallelograms, which of the following must be true?

Accepted Answer

All squares are parallelograms.

Answer

This question relies on the transitive property of logical statements. If all squares are rectangles, and all rectangles are parallelograms, then it logically follows that all squares must also possess the properties of parallelograms. This chain of inclusion means squares are a subset of rectangles, which are a subset of parallelograms.

Question 2

If A is greater than B, and B is greater than C, which of the following must be true?

Accepted Answer

A is greater than C.

Answer

This question illustrates the transitive property of inequalities. If A is greater than B, and B is in turn greater than C, it logically follows that A must also be greater than C. This establishes a clear hierarchical relationship among the three quantities.

Question 3

Which of the following conclusions can be made from the statement: 'All birds have feathers'?

Accepted Answer

All birds have feathers, but not all animals do.

Answer

The statement 'All birds have feathers' defines a universal characteristic of birds. While it confirms that feathers are present on all birds, it does not imply that feathers are exclusive to birds or that every animal possesses them. Therefore, the most accurate conclusion is that this trait is specific to birds within the broader animal kingdom, but not all animals share it.

Question 4

If all mammals are warm-blooded and all warm-blooded animals have fur, which of the following is true?

Accepted Answer

All mammals have fur.

Answer

This is an example of a syllogism, a form of deductive reasoning. If all mammals fall into the category of warm-blooded animals, and all warm-blooded animals possess fur, then it logically follows that all mammals must also possess fur. The characteristic of having fur is directly extended to mammals through the intermediate classification of being warm-blooded.

Question 5

Which of the following is an example of a valid conclusion based on the following premise? 'If it rains tomorrow, we will go to the park.'

Accepted Answer

If it rains tomorrow, we will go to the park.

Answer

A valid conclusion based on a premise is often the premise itself, as it is inherently true if the premise is true. The statement 'If it rains tomorrow, we will go to the park' is a conditional statement. The correct answer simply reiterates this original premise, which is always a logically sound conclusion.
