Use this check for every sentence in the level.
First: identify إِذَا, لَوْ or the earlier conditional opening.
Second: decide whether the meaning is expected time or an unfulfilled past condition.
Third: mark the complete condition and answer clauses.
Fourth: if لَوْ is used, check affirmative لَـ versus a negative answer without it.
Fifth: apply jussive only to an imperfect verb; leave a past verb built.
Finally, give one complete idiomatic translation.
