First of all, it is not an error to use the passive voice. Many books on style discourage overuse of the passive, but there is nothing erroneous about it. There are some cases where the passive voice is superior to the active voice (particularly in complex sentences.)
Second, there are particular situations where the passive voice is less useful than the ...
I am not sure what the second sentence means. Perhaps it's "You need a book grant to purchase one" or "You need special permission to use your grant for this book".
Your best solution is to rewrite the second sentence. Use active or passive voice, but be clear.

The difference, once you know it, is actually pretty ...
Why can't I write this: "What time IS the pharmacy open?"
You most certainly can.
In this case, "is" is a state of being: the pharmacy is in the state of openness between 8AM to 9PM.
"When does the pharmacy open?"
That also works, because the pharmacy is "doing" (where "do" is the root of "does" ...
