Meaning: 'Tolerate' means to allow something to happen or exist, even if you do not agree with it or like it.

Wrong options:

• believe: 'Believe' is a verb that means to accept something as true, which does not fit the context of dealing with free riders, as it does not convey the action of enduring or accepting them.
• overlook: 'Overlook' means to fail to notice something, which implies neglect rather than acceptance, making it unsuitable in this context where a conscious choice is being discussed.
• misunderstand: 'Misunderstand' means to interpret something incorrectly, which does not relate to the action of dealing with free riders and does not fit grammatically in the sentence.

Correct answer: effects

Explanation: The word 'effects' is appropriate here as it refers to the consequences or results of the irresponsibility mentioned earlier in the sentence. It fits grammatically as a noun that aligns with the context of discussing the outcomes of irresponsible behavior, making it the correct choice.

Meaning: 'Effects' refers to the results or outcomes that occur due to certain actions or behaviors, in this case, the irresponsibility of some individuals.

Wrong options:

• contents: 'Contents' refers to the items or material contained within something, which does not relate to the consequences of irresponsibility and is not suitable in this context.
• appearances: 'Appearances' refers to the way something looks or seems, which does not connect with the idea of consequences and is irrelevant here.
• causes: 'Causes' refers to the reasons something happens, which is the opposite of what is being discussed; the sentence is about the results of irresponsibility, not the reasons behind it.

Correct answer: educate

Explanation: The word 'educate' is the correct choice as it is a verb that means to provide knowledge or training. In this context, it fits grammatically and contextually, as the sentence discusses the role of the state in improving the behavior of irresponsible individuals through knowledge and awareness.

Meaning: 'Educate' means to teach someone about a particular subject or to provide them with information that can help them make better choices.

Wrong options:

• breach: 'Breach' means to violate or break a law or agreement, which does not fit the context of improving behavior and is grammatically incorrect in this sentence.
• divide: 'Divide' means to separate into parts, which does not relate to the action of improving or teaching individuals and is not suitable here.
• muster: 'Muster' means to gather or assemble, which does not convey the idea of teaching or providing knowledge, making it an inappropriate choice in this context.

Correct answer: and

Explanation: The word 'and' is a conjunction that connects two related ideas, in this case, sexual and racial minorities. It fits grammatically as it links the two categories being discussed, maintaining the flow of the sentence and ensuring clarity in the message.

Meaning: 'And' is used to connect words or phrases that are similar or related, indicating that both sexual and racial minorities are being addressed together.

Wrong options:

• is: 'Is' is a verb that indicates existence or identity, which does not fit the context of connecting two categories and disrupts the grammatical structure of the sentence.
• are: 'Are' is also a verb that indicates existence but does not serve the purpose of connecting two nouns in this context, making it unsuitable.
• for: 'For' is a preposition that indicates purpose or direction, which does not function as a connector between the two groups mentioned and is grammatically incorrect in this context.
