I am wondering if anyone can help me with this cryptic question:-

What’s the foodie link? 1. 70-75, 2. 65-70, 4. 55-60, 7. <45

It has been driving me to dispair....Thanks in advance.

is "1. " part of the question, or is it the question number???

Is there meant to be a space between the numbers and the "." ??
