A.I. Explanation:

Correct answer: When

Explanation: The word 'When' introduces a temporal clause, indicating the time at which the terrorist attack occurs. This fits grammatically as it sets the context for the feelings described in the sentence, aligning with the overall meaning of the passage.

Meaning: 'When' refers to the time something happens, indicating a specific moment or period.

Wrong options:

• Just as: 'Just as' implies a simultaneous occurrence but does not fit the context of a specific event like a terrorist attack.
• Until: 'Until' suggests a limit or endpoint, which does not apply here as the sentence describes feelings that arise at the moment of the attack.
• Afterwards: 'Afterwards' indicates a time following an event, which contradicts the immediate context of feelings during the attack.
• By the time: 'By the time' suggests a condition that must be met before something else occurs, which is not the intended meaning in this context.

Correct answer: the same

Explanation: The phrase 'the same' indicates that the feelings experienced during a terrorist attack are identical to those felt during other traumatic events. This fits grammatically and contextually, as it emphasizes the similarity of emotional responses.

Meaning: 'The same' means identical or not different, highlighting that the feelings are consistent across different situations.

Wrong options:

• exact: 'Exact' refers to precision and does not convey the idea of similarity in feelings, making it contextually inappropriate.
• alike: 'Alike' is an adjective that does not fit grammatically in this structure, which requires a noun phrase.
• similarly: 'Similarly' is an adverb and does not fit grammatically as it cannot directly modify 'feelings' in this context.
• like: 'Like' is a preposition that would require a different grammatical structure, making it unsuitable here.

Correct answer: another

Explanation: The word 'another' is used to refer to an additional item of the same type, which fits grammatically and contextually as it introduces another major event similar to those previously mentioned.

Meaning: 'Another' means one more or an additional one, indicating that there are multiple types of major events.

Wrong options:

• the other: 'The other' implies a specific alternative among two, which does not fit as the sentence refers to any additional major event.
• others: 'Others' is plural and does not match the singular form required in this context.
• other: 'Other' is an adjective that does not fit grammatically as it lacks the necessary article to precede 'major event'.

Correct answer: about

Explanation: The preposition 'about' is used to indicate concern regarding a subject, which fits grammatically and contextually as it expresses the experts' worry for children experiencing tragic events.

Meaning: 'About' indicates the subject of concern or interest, in this case, the children affected by tragic events.

Wrong options:

• of: 'Of' does not convey concern and is grammatically incorrect in this context as it does not indicate the subject of worry.
• to: 'To' implies direction or purpose, which does not fit the context of expressing concern.
• with: 'With' suggests accompaniment rather than concern, making it unsuitable in this context.
• against: 'Against' implies opposition, which does not align with the intended meaning of concern.

Correct answer: likely to

Explanation: The phrase 'likely to' indicates a high probability of developing emotional problems, fitting grammatically and contextually as it describes the increased risk for children experiencing tragic events.

Meaning: 'Likely to' means having a high chance of something happening, indicating that these children are at greater risk for emotional issues.

Wrong options:

• probably: 'Probably' is an adverb that suggests a possibility but does not fit grammatically in this structure, which requires a phrase indicating likelihood.
• dangerously: 'Dangerously' implies a risk but does not convey the probability of developing problems, making it contextually inappropriate.
• possibly: 'Possibly' suggests uncertainty and does not convey the strong likelihood intended in this context.
• bound to: 'Bound to' implies certainty rather than probability, which does not align with the intended meaning of likelihood.
