A. The harder you try, the farther you’ll get in life
A simile can be found when using "like" or "as" between two things. Example: I'm as happy as a clown.
Your question would be a metaphor. Both things are being compared to a science expieriment, probably meaning that they need to have an outcome, but it isn't known for sure if it will be a good or bad outcome.
Things like this can be taken many ways, so if you think something else, I'm sure it would work as well.
I believe it's: "<span>Mr. Frank believes the burglars will betray the annex residents; Anne does not."</span>
