Meaning: 'Encourage' means to give support, confidence, or hope to someone, in this case, motivating students to attend classes.

Wrong options:

• suggest: 'Suggest' implies offering an idea or recommendation, which lacks the proactive connotation needed in this context.
• force: 'Force' indicates coercion, which does not align with the supportive approach intended by the school.
• make: 'Make' is too vague and does not convey the positive motivation that 'encourage' does.

Correct answer: achieved

Explanation: The word 'achieved' is the correct verb form that indicates successfully reaching a goal, which in this case is a 100% attendance record. It fits grammatically and contextually as it reflects the accomplishment of the students.

Meaning: 'Achieved' means to successfully reach a desired objective or result, specifically in this context, maintaining perfect attendance.

Wrong options:

• succeeded: 'Succeeded' is a synonym but is less specific in this context, as it does not directly relate to attendance records.
• made: 'Made' is too general and does not convey the sense of accomplishment that 'achieved' does.
• realised: 'Realised' implies becoming aware of something rather than accomplishing a goal, making it unsuitable here.

Correct answer: rewarded

Explanation: The word 'rewarded' is the correct past participle that indicates giving a prize or recognition for an achievement. It fits both grammatically and contextually, as it describes the action taken by the school for students with perfect attendance.

Meaning: 'Rewarded' means to give something in recognition of a service, effort, or achievement, in this case, a trip for good attendance.

Wrong options:

• given: 'Given' is too vague and does not convey the sense of a positive acknowledgment that 'rewarded' implies.
• won: 'Won' suggests a competitive context, which does not apply here as attendance is not a competition.
• compensated: 'Compensated' implies a payment for loss or injury, which does not fit the context of rewarding students for attendance.

Correct answer: outdoor

Explanation: The word 'outdoor' is an adjective that describes activities taking place outside. It fits grammatically and contextually as it specifies the type of activities available during the trip.

Meaning: 'Outdoor' refers to activities that occur outside, such as climbing and rafting, which are relevant to the context of the trip.

Wrong options:

• outside: 'Outside' is an adverb and does not function as an adjective to describe activities.
• risk: 'Risk' refers to the possibility of harm or loss, which does not describe the nature of the activities.
• danger: 'Danger' indicates a threat or harm, which is not relevant to the description of the activities offered.

Correct answer: maintaining

Explanation: The word 'maintaining' is a gerund that indicates the ongoing action of keeping up with his attendance. It fits grammatically and contextually as it reflects his concern about continuing his perfect attendance record.

Meaning: 'Maintaining' means to keep something in a particular state or condition, in this case, his 100% attendance.

Wrong options:

• filling: 'Filling' implies completing something, which does not relate to the concept of attendance.
• guarding: 'Guarding' suggests protecting something, which does not fit the context of attendance.
• succeeding: 'Succeeding' implies achieving a goal but does not convey the ongoing effort required to keep up attendance.

Correct answer: eventually

Explanation: The word 'eventually' is an adverb that indicates something happening after a period of time. It fits grammatically and contextually as it describes the timing of his admission to his mother.

Meaning: 'Eventually' means at a later time or after some delay, indicating that he admitted the truth after some time had passed.

Wrong options:

• lastly: 'Lastly' implies the final point in a sequence, which does not fit the context of his admission.
• actually: 'Actually' is used to emphasize the truth of a statement but does not convey the timing aspect needed here.
• fortunately: 'Fortunately' implies a positive outcome, which does not accurately describe the situation of his admission.
