FCE Use of English Part 1, Night Vision

Answers and explanations

  1. D – course. As opposed to ‘time’ and ‘period’, course is a less defined unit of time and can often include the very beginning as well as the present state. ‘Process’ could work in a phrase like ‘during the process of evolution’.
  2. A – expense ‘At the expense of something’ is a set expression; here it means that ‘something’ had to be sacrificed in order to achieve something else. In other words, night vision was achieved only through a partial loss of colour vision.
  3. C – survival Context is key here, and for that reason you might want to read the sentence till the end to fully understand it. The sentence focuses on the aspect of survival – hunting for food, to be more exact.
  4. B – prey We did mention ‘food’ previously, but it should not be understood literally. A hunter does not catch food, they catch (or hunt) their prey. ‘Victim’ is a word that is more commonly used to refer to humans than animals, except for figurative examples (‘Pets can often be victims of violence’).
  5. C – make The phrasal verb ‘make use of something’ means to find application to something that is available. Another possible phrase in this context is‘to put something TO use’. You can also let SOMEONE use something or find use FOR something.
  6. B – adjusting The idea is to adapt to something, in this case, to changing light levels. ‘Changing’ is too broad and general. C does not work because it is ‘focusing ON something’. ‘Moving’ is not fitting the idea of change.
  7. A – respectively Even if you don’t know the word ‘respectively’, knowledge of punctuation can help you. The only two words that require a comma in this context is ‘respectively’ and ‘obviously’, and the second one clearly does not make sense here, as this function of the pupil is not common knowledge. We use ‘respectively’ to refer to two or more things mentioned in the order they are used in the phrase or sentence.
  8. C – make out To manage to see or hear something, especially if it is difficult for some reason.
