Correct Answer: A
Why this is correct: The word position tells us a job or post someone holds, and appointment expresses the same idea - a post you are given.
Tips: Memory trick: when you are 'appointed' to a 'position', you get the seat - both mean a job you take up.
Why the other options are wrong:
- B: work means tasks or effort in general, not one particular job title.
- C: business means trade or company matters, which is a different idea from a job post.
- D: employment means the state of having a job overall, not the specific new post he was promoted to.
Key Vocabulary:
- position = appointment = a job post
- promoted = moved up
Correct Answer: A
Why this is correct: Fit and install both mean to put equipment into place ready to use - they are interchangeable here.
Tips: Memory trick: engineers 'fit' new lights and 'install' them - both mean putting them in ready to work.
Why the other options are wrong:
- B: fix means to mend or fasten firmly - close, but the sentence is about setting up new equipment, not repairing it.
- C: place means simply to put something somewhere, without the sense of setting it up to work.
- D: replace means to put something new in place of the old, which is more than just fitting the equipment.
Key Vocabulary:
- fit = install = set up in place
- equipment = tools and machines
Correct Answer: A
Why this is correct: The sentence uses comprises to mean 'is made up of' or 'includes', and contains has the same meaning - holds inside.
Tips: Memory trick: a report that 'comprises' data 'contains' data - it holds all those parts inside.
Why the other options are wrong:
- C: composes looks like comprises, but it means to make up as a writer, like composing music - a surface trap.
- D: consists does mean 'is made up of', but it needs 'of' after it - we say 'consists of', so it does not fit the grammar here.
- B: complements means to complete or go well with something, and it also sounds like 'compliments' - neither meaning fits.
Key Vocabulary:
- comprises = contains = is made up of
- concise = short and clear
Correct Answer: C
Why this is correct: Think of exhausted as meaning completely used up. Run out of means the same - to have none left.
Tips: Memory trick: when your energy is 'exhausted', you have 'run out of' it - the tank is empty.
Why the other options are wrong:
- A: cleaned up means tidied or removed mess, not used something up entirely.
- B: done away with means got rid of or abolished, which is a choice to remove, not using it all up.
- D: got through to means reached or made contact with someone, which does not fit fuel being used up.
Key Vocabulary:
- exhausted = run out of = used up completely
- fossil fuels = coal, oil and gas
Correct Answer: B
Why this is correct: Inevitably is a direct synonym of unavoidably - both mean something is sure to happen and cannot be stopped.
Tips: Memory trick: 'unavoidable' and 'inevitable' both mean you cannot dodge it - it will happen no matter what.
Why the other options are wrong:
- D: constantly means all the time or again and again, which is about how often, not about being unavoidable.
- C: incidentally means by the way or by chance, the opposite of something bound to happen.
- A: subsequently means afterwards or later, which is about time order, not about being certain to occur.
Key Vocabulary:
- unavoidably = inevitably = sure to happen
- obstacles = things in your way
Correct Answer: D
Why this is correct: When the sentence says profound, it means very deep and far-reaching, and serious is another way to say that its effects really matter.
Tips: Memory trick: a 'profound' effect and a 'serious' effect both run deep and matter a great deal.
Why the other options are wrong:
- B: formidable means powerful and a little frightening or hard to deal with, not deep and important.
- C: devastating means causing terrible damage - that is too negative for effects that are simply deep and important.
- A: utter means complete or total, like 'utter nonsense', which does not describe how deep the effects are.
Key Vocabulary:
- profound = serious = deep and important
- implications = possible effects
