A.I. Explanation:

Correct answer: managed

Explanation: The word 'managed' fits grammatically as it indicates successfully achieving something despite challenges, aligning with the context of preparing for an exam. It conveys a sense of effort and accomplishment, which is appropriate here.

Meaning: 'Managed' means to succeed in doing something, especially after a lot of effort, indicating that the speaker was able to achieve their goal of getting enough points for the scholarship.

Wrong options:

• succeeded: While 'succeeded' also indicates achievement, it lacks the nuance of effort and struggle implied by 'managed.'
• failed: 'Failed' conveys the opposite meaning, indicating that the speaker did not achieve their goal, which contradicts the context of being happy about getting points.
• accomplished: 'Accomplished' suggests a completed task but does not convey the sense of overcoming challenges as effectively as 'managed' does.

Correct answer: proud

Explanation: The word 'proud' fits well as it expresses a positive emotional response to one's achievements, aligning with the context of celebrating success after hard work.

Meaning: 'Proud' means feeling deep pleasure or satisfaction as a result of one's own achievements or qualities, indicating the speaker's happiness about their performance.

Wrong options:

• happy: While 'happy' is a positive emotion, it is more general and does not specifically convey the sense of self-satisfaction that 'proud' does in this context.
• eager: 'Eager' implies a strong desire or enthusiasm, which does not fit the context of reflecting on one's achievements.
• pleased: 'Pleased' is similar to 'happy' but lacks the depth of self-satisfaction that 'proud' conveys.

Correct answer: up

Explanation: The phrase 'ring up' is a common idiomatic expression meaning to make a phone call, making 'up' the correct choice in this context.

Meaning: 'Up' in this context is part of the phrasal verb 'ring up,' which means to call someone on the phone.

Wrong options:

• on: 'On' does not form a recognized phrasal verb with 'ring' and does not convey the action of making a phone call.
• down: 'Down' does not fit with 'ring' in this context and does not convey any meaning related to making a call.
• off: 'Off' does not work with 'ring' and does not relate to the action of calling someone.

Correct answer: spare

Explanation: The word 'spare' fits grammatically as it refers to having extra or additional change available, which is necessary for making a call in this context.

Meaning: 'Spare' means extra or additional, indicating that the speaker did not have any extra change available for the call.

Wrong options:

• extra: While 'extra' is similar in meaning, it does not fit grammatically in this context as 'spare' is the more commonly used term for this situation.
• loose: 'Loose' refers to something not tight or secure, which does not relate to the context of having change for a call.
• free: 'Free' typically refers to something that costs nothing, which does not fit the context of having change available.

Correct answer: postponed

Explanation: The word 'postponed' fits well as it indicates that the surprise will be delayed until a later time, aligning with the context of having to wait until tomorrow.

Meaning: 'Postponed' means to delay an event or action to a later time, indicating that the surprise cannot happen today and will occur tomorrow instead.

Wrong options:

• cancelled: 'Cancelled' means that the event will not happen at all, which contradicts the idea that it will happen later.
• rescheduled: 'Rescheduled' implies that a new time has been set, which is not indicated in the context; the speaker simply states it will happen tomorrow without specifying a new time.
• moved: 'Moved' is vague and does not clearly convey the idea of delaying an event as effectively as 'postponed' does.
