I have a major problem with this question, and here is why.
There are three boxes that an officer needs to tick, as it were, to receive a Mayor’s Commendation.
1. eligibility
2. whether he went beyond “what could reasonably expected of a police officer”
3. whether the act saved someone’s life
As others did, I quickly narrowed the list down to A and B.
Now, the major problem that I have with A and the reason that I cannot choose A over B are this.
How do we know that Franklin and Penn actually saved a child’s life?The wording of A is such that we cannot ascertain that.
A says, “in saving a child, F and P risked their lives.” OK, but did they, in end, save the child’s life?
The situation may have turned out to be:
In saving a child from drowning, F and P risked their lives, but to no avail, and in the end, failed to save the child’s life.
We just cannot know whether they succeeded in saving the child’s life.
“In doing something” and “having done something”, these are two different things. "In doing something" only means, in my opinion, the simultaneity to the act in the main clause, but not the completion of the act.
Let’s consider an analogous example to make this point clear.
The condition to be met for graduation: a student has written an essay.
In writing an essay, John had a brilliant idea for a business, so John quit school and became an entrepreneur. → OK, so in the end, John did not write an essay. John did engage in the act of writing an essay, but did not complete the essay.
Franklin and Penn did engage in the act of saving a child'd life, but that is as far as A tells.
This is a major sticking point in seeing A as the right answer.
