Answers
Answers are given in capital letters to make them easier to read. This is important for hand written answers, but less important for computer based IELTS.
- WRENCH
- You cannot have “a wrench” because the word “a” is given in the question statement and is not missing. Your task is only to provide what is missing.
- EMAILED
- MONTHS
- SELF-RELIANT
- You cannot have “more self-reliant”. The words “to a much greater extent” already supplies the meaning of “more” in the question statement. This means, you do not need to have that meaning twice in the sentence.
- LAUNCHING COSTS
- This cannot be singular. You cannot have “launching cost” as an answer. If it was singular, you would need an article: “a lower launch cost.”. Because the sentence must be grammatically correct, you must copy it as given in the passage – as a plural.
- You also cannot have “costs” only. The meaning would be wrong. This isn’t about general costs being lower, it is about launch costs being lower. It is a specific answer which requires both words or the meaning is lost.
- FIRST OBJECT
- The answer cannot be “socket wrench” because the grammar and meaning of the sentence would be wrong. Looking at the grammar, the sentence would have “a” instead of “the” if the answer was “socket wrench”.
- ON THE FLY = on the go / quickly / while moving / in motion
- This term does have other meanings depending on the context it is used.
