Hi,
Why is were used here, subject is depletion which is singular.
Something about conditionals.
TYPE 0 CONDITIONALSIf(or when) + present tense | present tense
If(or when) + past tense | past tense
If and when can be interchangeably used only when we are talking about situations that are definitely going to happen.
If a situation is dependent on something, then we use "if".
If it rains, I won't go out.
correctWhen it rains, I won't go out.
WrongIf you heat water it evaporates.
correctWhen you heat water it evaporates.
correctRemember, Type 0 is the only conditional type in which you can use "if" and "when" interchangeably.
TYPE 1 CONDITIONAL (Things are likely to happen here)
The type 1 conditional expresses a future scenario that might occur. Assuming that the condition is fulfilled, the outcome is likely to happen.
If + present tense | will (may/might/can/could/should) + verb
If I get paid, I will go shopping.
If I see that man, I may say something.
TYPE 2 CONDITIONAL (Things are unlikely to happen here)
This can either refer to future hypotheticals that are unlikely to be true or present situations that are untrue or impossible.
If + simple past | would
If I were president, I would rule.
If I were rich, I would travel the world.
If I were invisible, I would rob the bank.
TYPE 3 CONDITIONALS The unreal situation in the past, with reference to the hypothetical outcome that would result also in the past.
If + past perfect | conditional perfect
If I had known you were going to react, I would have not done that.
If you had seen the movie, I would have/could have taken you out to watch its sequel.
