The correct answer is option 2 i.e. disseminate.

Explanation       

Promulgated means promoted or made widely known (an idea or cause).
Let us look at the meanings of the given options-

• Prune means reduce the extent of (something) by removing superfluous or unwanted parts.
• Disseminate means spread (something, especially information) widely.
• Concatenate means link (things) together in a chain or series.
• Pertain means be appropriate, related, or applicable to.

Clearly, 'disseminate' is closest in meaning.

The correct answer is option 1 i.e. only (i).

Explanation  

• For statement (i), we need a direct link between novels and authors which is possible through their connections to stories.
• Now, all stories have an author. Therefore, the novels which are stories will have an author.
• For statement (ii), we need a direct link between books and stories which is possible through their connections to novels.
• Now, no book is a novel and some novels are stories. We cannot say that all books are stories.

Clearly, only statement (i) can be inferred.

Options 1 and 2 are logically incorrect. 

Option 3 frames a proper meaning that when it comes to supporting women, a woman should not have national boundaries. 

Option 4 cannot be correct as the sentence does not talk about legal rights at all.

It is not mentioned that Rajan wanted to work only in a group thus option 1 is invalid.

It is not mentioned that the two of them were grouped together. It is clear that it was a matter of their choice and Sajan had chosen to work individually.Thus 2 is invalid.

It is mentioned that Sajan explained to Rajan that he liked to work independently which makes it clear that he had not given in to his request. Thus 3 is invalid too.

It can be understood that Rajan was unhappy with Sajan working on his own as he had expected that they would work together. His expectation was not met. Thus option 4 is logically valid here.

The correct answer is option 1.

Explanation        

• The given paragraph describes the Indian economy.
• It states that the lockdown has made the weaknesses of the Indian economy visible.
• This means that even before the lockdown the economy was not very strong.
• No other option can be inferred from the paragraph.

The correct answer is option 2.

Explanation

• The given passage focusses on the ties between the two countries i.e. India and UAE.
• It is clear that the author is a citizen of UAE.
• The author has stated that no community other than India that has contributed more to the building of the basic structure of UAE.
• No other option can be inferred from the given passage.

The correct answer is option 4 i.e. neither (i) and (ii).

Explanation  

• It is mentioned that 'every fish is a crocodile'. It is also mentioned that not all crocodiles are mammals, and that no mammal is a bird.
• We cannot infer statement (i) from the given sentences. Since every fish is a crocodile, some fishes can be mammals too.
• Also, since no mammal is a bird, crocodiles(it is already mentioned that some crocodiles are mammals) cannot be birds too. 

Hence, we can infer neither (i) nor (ii).

The statement in option 1 is one of the reasons to not worry about wearing seat belts. Thus, it is supporting the conclusion and does not weaken it. Therefore, option 1 gets eliminated.

To refute the conclusion in this argument, we need to prove that automobile drivers and passengers not wearing seat belts harm other people as well. The harm could be in the form of a physical injury or costs associated with damage to vehicles.

The higher insurance rates indicate that in most accident cases, the chances of the vehicle getting damaged or the passengers getting hurt are high. Thus, this can be considered as a harm to the insurance providers.

Thus, if the second statement is true it will help weaken the conclusion drawn in the question.

The statement in option 3 is irrelevant as it talks about passengers of airplanes and not those of automobiles.

The statement in option 4 does not explain the harm caused to others while driving automobiles without seat belts.

We cannot be certain that the fatalities caused in states without mandatory laws are those of people not wearing seat belts.

Hence, option 2 most seriously weakens the conclusion drawn above.
