Improve the bracketed part of the sentence or select "No improvement":\n"Take out your binoculars and (will see) the Andromeda galaxy."

Introduction / Context:
This question tests basic sentence structure and verb form in coordinated imperatives. The sentence begins with an imperative instruction "Take out your binoculars" and then continues with a second action linked by "and". The bracketed part "will see" must be corrected or left unchanged, depending on whether it fits this imperative pattern.

Given Data / Assumptions:

• Sentence: "Take out your binoculars and (will see) the Andromeda galaxy."
• The subject "you" is understood, as is usual in imperatives.
• We assume the intention is to give a direct instruction and describe what happens as a result.
• Options: "see", "saw", "seeing", "No improvement".

Concept / Approach:
In English, when two actions share the same understood subject in an imperative, both verbs generally appear in the base form: "Take out your notebook and write", "Come in and sit down". The auxiliary "will" is not used in the second part of a simple imperative, because that would turn it into a futurity statement rather than a coordinated instruction. Therefore, we need to remove "will" and use the bare infinitive "see" to preserve the imperative structure.

Step-by-Step Solution:
Step 1: Recognise that "Take out your binoculars" is an imperative, giving a command or instruction.Step 2: Understand that the same subject "you" applies to the second action after "and". So the pattern should be "Take out your binoculars and see the Andromeda galaxy."Step 3: Examine option (a) "see". This matches the base verb form required in a second imperative clause.Step 4: Examine option (b) "saw". This is the simple past form, which does not fit with an imperative structure.Step 5: Examine option (c) "seeing". This is a participle or gerund, and would require a different structure, such as "You will be seeing", which is not what the sentence uses.Step 6: Examine option (d) "No improvement". Retaining "will see" would lead to "Take out your binoculars and will see the Andromeda galaxy", which is ungrammatical because the understood subject "you" does not carry over correctly to "will see".

Verification / Alternative check:
Replace the bracketed part with option (a): "Take out your binoculars and see the Andromeda galaxy." This sounds like a natural instruction that you might hear in a planetarium or astronomy lesson. It uses two coordinated imperatives directed to the same person. Trying the other options quickly confirms their incorrectness: "and saw the Andromeda galaxy" sounds like a narrative, not an instruction, and "and seeing the Andromeda galaxy" is incomplete as a clause.

Why Other Options Are Wrong:

• Option (b) "saw": Past tense, inconsistent with the imperative mood and the rest of the sentence.
• Option (c) "seeing": A non-finite form that cannot stand alone as a second imperative clause.
• Option (d) "No improvement": Leaves the incorrect "will see" in the sentence, resulting in faulty structure.

Common Pitfalls:
Candidates may think that "will see" is acceptable because it expresses a future result. However, in an exam sentence improvement task, the focus is on grammatical correctness and standard patterns, not on overly literal expressions. A good rule of thumb is that when two imperative actions are joined by "and", both should use the base verb form without auxiliaries like "will".

Final Answer:
The correct improvement is "see", so the sentence should read: "Take out your binoculars and see the Andromeda galaxy."
