Understanding the Passage and the Blank

The passage discusses how easily people accept ideas, even absurd or illogical ones, based solely on the authority of the person asserting them. This tendency is highlighted as being particularly prevalent in areas like religion and politics. The blank we need to fill is in the sentence: "Mere assertion _____________ the leaders seems sufficient for the multitude of followers to acquiesce."

This sentence explains the mechanism by which followers accept ideas. It states that simple assertion, originating from the leaders, is enough for the followers to agree or comply (acquiesce).

Analyzing the Options for the Blank

Let's look at the given options and consider which one best fits the meaning of the sentence:

• Option 1: With - "Mere assertion with the leaders..." This suggests the assertion is made alongside or in agreement with the leaders. It doesn't clearly indicate that the leaders are the source of the assertion.
• Option 2: By - "Mere assertion by the leaders..." This is a standard grammatical construction to indicate the agent performing an action, especially when the action is a noun (assertion). "Assertion by the leaders" means the assertion made by the leaders. This fits the context that the leaders are the ones asserting the ideas.
• Option 3: To - "Mere assertion to the leaders..." This implies the assertion is directed towards the leaders, which is the opposite of what the sentence intends. The assertion is coming from the leaders to the followers.
• Option 4: At - "Mere assertion at the leaders..." This could imply direction, similar to "to," or potentially hostility, neither of which fits the context of leaders asserting ideas to followers.

Selecting the Correct Preposition: 'By'

Based on the analysis, the preposition that correctly identifies the leaders as the source or agents of the assertion is "By". The phrase "assertion by the leaders" clearly conveys that the leaders are making the assertions mentioned in the passage.

Let's read the sentence with "By" inserted:

"Mere assertion By the leaders seems sufficient for the multitude of followers to acquiesce."

This sentence now logically follows the preceding sentences, explaining how assertion originating from figures claiming authority (leaders) leads to acceptance by the masses (multitude of followers).

Explanation of Grammatical Usage

The preposition 'by' is often used to indicate the agent performing an action, especially in passive constructions or when the action is represented as a noun (like 'assertion'). For example:

• The book was written by him. (Passive voice)
• The discovery by the scientists changed everything. (Noun form)

In our case, "assertion by the leaders" uses 'by' in a similar way to indicate that the assertion is performed by the leaders.

Connecting to the Passage Theme

The overall theme of the passage is the uncritical acceptance of ideas based on authority. The sentence we are examining provides a specific example of this: mere assertion by the leaders is enough for followers to accept ideas without question. This reinforces the idea that the source of the assertion (the leader) holds significant weight, often overriding the logic or truth of the idea itself.

Additional Information: Acquiescence and Authority

The word "acquiesce" means to accept something reluctantly but without protest. In the context of the passage, followers acquiesce to the assertions made by leaders. This concept is closely related to the idea of authority figures and their influence on group behavior and belief systems.

The passage suggests a critical look at why people accept information. It implies that relying solely on who is saying something (authority) rather than evaluating what is being said (logic, evidence) can lead to the acceptance of "absurd" or "illogical" ideas.
