The aim of many scientific experiments is to demonstrate whether a suggested explanation for something is supported by enough evidence.

Correct Answer: C
Why this is correct: When the sentence says demonstrate, it means to make something clear by proving it, and show is another way to say that.
Tips: Memory trick: a science 'demo' shows you what happens - to 'demonstrate' is to 'show' it clearly.
Why the other options are wrong:
- A: ask means to put a question or make a request, which is not the same as proving something is true.
- D: explain is close - it means to make something clear with reasons - but demonstrate means to prove it with evidence, not just talk it through.
- B: try means to attempt or have a go, which does not carry the idea of showing that something is supported by evidence.
Key Vocabulary:
- demonstrate = show = prove
- evidence = facts that support
Correct Answer: B
Why this is correct: Probable is a direct synonym of likely - both mean something has a good chance of happening.
Tips: Memory trick: if rain is 'likely', it is 'probable' - both mean it will most likely happen.
Why the other options are wrong:
- C: actual means real or true, which is about what is already the case, not about what may happen.
- D: potential means possible in the future, but it does not say how good the chance is the way likely does.
- A: reliable means able to be trusted, which is a different idea from something being likely to happen.
Key Vocabulary:
- likely = probable = a good chance
- influence = effect on
Correct Answer: B
Why this is correct: The word expected tells us students are meant and obliged to do something, and required expresses the same idea - it must be done.
Tips: Memory trick: what you are 'expected' to do is 'required' of you - it is part of the deal.
Why the other options are wrong:
- A: demanded means forcefully ordered, which is too strong and pushy for the steady expectation of a course.
- C: planned means arranged in advance, but being expected to do something is about a rule, not a plan.
- D: assumed means taken for granted or supposed, which does not mean students must do the placement.
Key Vocabulary:
- expected = required = must do
- placement = work experience
Correct Answer: B
Why this is correct: In this sentence, Reflecting on means thinking carefully about something, and Considering means exactly that - weighing it up in your mind.
Tips: Memory trick: to 'reflect on' a result is to 'consider' it - both mean giving it careful thought.
Why the other options are wrong:
- C: Recollecting means remembering or calling to mind, which is only about the past, not thinking it through.
- D: Inspecting means examining something closely, usually a physical object, not turning ideas over in your head.
- A: Regarding means 'about' or 'concerning', like 'regarding your email' - it does not mean to think carefully.
Key Vocabulary:
- reflecting on = considering = thinking carefully about
- critical = very important
Correct Answer: C
Why this is correct: Attributes and qualities both mean the good characteristics that someone has - they are interchangeable here.
Tips: Memory trick: a good vet's 'attributes' are their 'qualities' - the strong points they bring to the job.
Why the other options are wrong:
- B: facets means the different sides or aspects of something, not the strong characteristics a person has.
- D: aspects means parts or features of something - close, but it points to sides of a thing, not personal qualities.
- A: properties means the features of a material or object, like the properties of metal, not human qualities.
Key Vocabulary:
- attributes = qualities = good characteristics
- essential = necessary
Correct Answer: C
Why this is correct: Both dwelling on something and mulling it over mean turning a thought over in your mind again and again - pick either and the sentence reads the same.
Tips: Memory trick: to 'dwell on' a failure is to 'mull it over' - both mean you keep chewing it over in your head.
Why the other options are wrong:
- D: looking through means scanning or reading over pages, not fixing your mind on one thought.
- B: drawing on means using something as a resource or source, which is not the same as thinking hard about it.
- A: storing up means saving something for later, not dwelling on it now.
Key Vocabulary:
- dwelling on = mulling over = keep thinking about
- learning opportunity = a chance to learn
