# Since Oscar Received Extensive Training in How to Repair Motorcycles, He is Able to Repair Many of Their Most Common Mechanical Problems. - Logical Reasoning

MCQ

Since Oscar received extensive training in how to repair motorcycles, he is able to repair many of their most common mechanical problems. However, Oscar does not understand how internal combustion engines work. When Oscar was given Lucy’s motorcycle to repair, he was able to fix the problem, despite the fact that he did not understand what was causing it.

From the above paragraph, which of the following can be properly inferred?

#### Options

• The problem with Lucy’s motorcycle involved its engine

• Not all mechanical problems can be repaired only by mechanics who understand how an internal combustion engine works

• At least some good mechanics are able to fix mechanical problems without an understanding of what is causing them

• Oscar’s mechanical training in how to repair motorcycles was incomplete

#### Solution

Not all mechanical problems can be repaired only by mechanics who understand how an internal combustion engine works

Explanation:

In the question, Oscar was able to repair the motorcycle despite not knowing what was causing the problem’. It is also known that he has received extensive training, can repair most mechanical problems and also does not understand how internal combustion engines work. We can clearly infer from here that there are some mechanical problems that do not require the understanding of internal combustion engines for solving them. The answer is  clearly 'Oscar’s mechanical training in how to repair motorcycles was incomplete.'
