Meaning: 'Dreaming' refers to the act of imagining or hoping for something, often related to aspirations or desires.

Wrong options:

• envisioning: While 'envisioning' suggests imagining, it is more formal and less commonly used in this context, making it less suitable for the tone of the sentence.
• contemplating: 'Contemplating' implies deep thought rather than a light-hearted aspiration, which does not fit the playful context of children drawing.
• begging: 'Begging' indicates a strong request or plea, which is unrelated to the context of children drawing and dreaming about their future.

Correct answer: such

Explanation: The word 'such' is used to refer to a specific type or category, in this case, a teenager with aspirations similar to those of the children mentioned earlier. It fits grammatically and contextually, linking Jason Hill to the previous discussion about children dreaming of being pilots.

Meaning: 'Such' means 'of the kind previously mentioned,' emphasizing that Jason Hill is one of those teenagers who dream of aviation.

Wrong options:

• single: 'Single' implies one individual without the context of shared aspirations, which does not connect well with the previous mention of children dreaming.
• much: 'Much' is typically used with uncountable nouns or to indicate degree, making it grammatically incorrect in this context.
• alone: 'Alone' suggests isolation, which contradicts the idea of being part of a group of dreamers, thus not fitting the context.

Correct answer: clung

Explanation: The word 'clung' is the past tense of 'cling,' which means to hold on tightly to something. It fits grammatically as it describes Jason's persistent attachment to his vision, aligning well with the context of determination and aspiration.

Meaning: 'Clung' means to hold on firmly to something, indicating Jason's strong commitment to his dream despite challenges.

Wrong options:

• glued: 'Glued' suggests a physical attachment rather than an emotional or aspirational one, making it less appropriate in this context.
• stuck: 'Stuck' implies being unable to move, which does not convey the active pursuit of a dream as effectively as 'clung.'
• pasted: 'Pasted' is more about adhering something physically and does not convey the emotional connection to his vision.

Correct answer: to

Explanation: The word 'to' is a preposition that indicates direction or relation, fitting grammatically and contextually as it introduces the recipient of the revelation about Jason's dream. It connects the action of revealing to the audience, which is the world.

Meaning: 'To' indicates direction or relation, in this case, showing that the revelation was directed towards the world.

Wrong options:

• in: 'In' would suggest being inside something, which does not fit the context of revealing a dream to the world.
• over: 'Over' implies a sense of covering or being above, which does not convey the intended meaning of sharing or revealing.
• for: 'For' suggests purpose or benefit, which does not accurately describe the act of revealing something to an audience.
