Here's the question statement from last week's lesson:
The graph below shows the average daily spend of three categories of international visitor to New Zealand from 1997 to 2017.
An easy way to paraphrase this sentence (for our introduction) is to change its order. I'll try to put the part about "visitors to New Zealand from 1997 to 2017" before the part about "the average daily spend".
Here's my introduction:
The line graph compares three types of traveller visiting New Zealand between 1997 and 2017 in terms of the average amount of money that they spent each day during their trips.
What was the key phrase that helped me to change the order of the sentence?
