You are composing a draft for an essay in which you wish to draw attention to both sides of a controversial issue. Which transition would be MOST fitting to use to express even-handedness on the subject?
A) however
B) by the way
C) on the other hand
D) interestingly enough
If you only focus on one side of a controversial issue, that makes it hard for readers to read your essay. So you should use the phrase "on the other hand".
