Critical Reasoning: Apply Thy Knowledge

Time has come to see application of Lesson 1 & Lesson 2 to real-time CAT Questions. Let's take the example from lesson 1:

Now, follow the following process to approach any Critical Reasoning Question:

Applying these to question above:

Step 1: Identify the question

Since the question is inference based, we have to find the option which is logically derived from the statement.

Step 2: Comprehend the argument

It is utmost important that we understand what question is asking. 

Step 3: Eliminate wrong answers                                

(A) Seasonal depression is one of the most easily treated forms of depression.

Different treatments of depression are even not discussed in the statement. Thus, we cannot say whether it is the most easily treated form of depression. Only the positive effect of eating baked items during winter season is discussed.  Hence, option A is eliminated.

(B) Lack of sunlight lowers the level of serotonin in the brain.

The level of serotonin is increased by eating carbohydrates and sugar, but statement doesn’t say that lack of sunlight  lowers the level of serotonin in the brain. Therefore, Option B is also eliminated.

(C) People are more likely to be depressed in midwinter than at other times of the year.

This could have been correct inference had ‘midwinter’ was mentioned. The statement talks about the winter season, not midwinter. Thus, option C is eliminated.

(D) Some antidepressants act by changing the brain‘s level of serotonin.

This can be inferred as it is based on our second premise. The statement clearly indicates that carbohydrates and sugar acts like some antidepressants as they boost the level of serotonin.

Thus, option D is the answer.

Wasn't that simple? Now, hone and test your CR skills by taking quick tests based on actual CAT questions, CRITICAL REASONING QUIZ.
