MET Mock Test - 2 - Question 28

Directions: In the given question, a sentence is divided into different segments. The first segment written in underline is fixed. Rearrange the other segments to form a coherent sentence. 

To try to answer (1) / enlisted the creative help of an (A) novel objects from hardened clay (B) artist adept in making (C) this question, the researchers first (D)

Detailed Solution for MET Mock Test - 2 - Question 28

The correct sequence is DACB. 

The first part should be followed by D. It is easier to make the AC link as the article "an" should be followed by "artist". Since novel objects can be made using clay, the CB link also makes sense. From the various options, only DACB makes a coherent sentence. Therefore, the correct sentence is - To try to answer this question, the researchers first enlisted the creative help of an artist adept in making novel objects from hardened clay. 

MET Mock Test - 2 - Question 29

In each of the following questions, find out which part of the sentence has an error. If there is no mistake, the answer is ‘No error’.

Because she is intelligent (1)/ therefore she secures (2)/ highest marks in her class.(3)/ No error (4)

Detailed Solution for MET Mock Test - 2 - Question 29

The error lies in the second part of the sentence. The sentence starts with the condition 'because' and the reason for it is mentioned in the later part. But 'therefore' as an adverb also states the condition. There should not be two conditions in a single sentence, so remove the adverb 'therefore' to avoid redundancy. Never use 'therefore' after 'because' in a sentence.

MET Mock Test - 2 - Question 30

The question has a main sentence, followed by four sentences labelled as A, B, C and D. Choose the ordered pair of statements where the first statement implies the second and both the statements are logically consistent with the main statement.

Sammy eats grilled chicken every time he goes to restaurant.

A. Sammy eats grilled chicken.

B. He goes to restaurant.

C. Sammy does not eat grilled chicken.

D. He does not go to restaurant.

Detailed Solution for MET Mock Test - 2 - Question 30

The logically consistent pairs for the statement, 'Sammy eats grilled chicken every time he goes to the restaurant' is 'If he goes to a restaurant, then Sammy eats grilled chicken'.

So, BA is a valid pair.

Therefore, option A is correct.
