Mind the Gap
Only one of these words belongs in the gap. Keep it, and throw the rest away.
Cloze questions are marked on two things at once, and you have to check both. First comes word class: after "was so" the sentence needs an adjective, a word that describes the path, which is why steeply (an adverb, describing how something happens) and steepness (a noun, the name of a quality) cannot go in however sensible they sound. Second comes meaning, and that is what separates the adjectives that are left: gentle is the right class but the wrong sense, because a gentle path would not force you to rest twice, and mountainous describes a whole region rather than one path. Steep passes both tests, so it is the answer. Read the finished sentence back to yourself every time, because your ear will catch an error your eye slides over.
What to say if they get stuck
- Read the whole sentence out loud with the word dropped in. If it sounds wrong, it is wrong.
- The word comes straight after "so", which means it has to describe the path itself, not how something was done.
- Two of the cards are the right kind of word. Pick the one whose meaning explains why you had to stop and rest.
