Boost vs heighten vs lift In the following multiple-choice exercise:
The mailing list has done much to ... the numbers of people attending.
A lift B encourage C heighten D boost
I know the correct answer is "boost" but I was wondering what makes "lift" and "heighten" incorrect, as they also mean "increase". Thank you |
