a) Whereas the indicative mood makes a statement, the subjunctive mood can be used to ask a question. The question usually involves deliberating about a certain course of action. The question may be either a real question (seeking an answer from the hearers) or a rhetorical one (just wanting consideration, with no answer expected). It is typically not asking "What?" or "Who?", but rather "How?", "Whether?", or "Where?" ("Could or Should I?"). The use of the subjunctive is indicating some uncertainty about the answer.
b) As was stated earlier about the overlap in use between the subjunctive mood and the
future indicative, the future indicative
c) It is usually translated into English using the future tense.
d) Real examples (rather than rhetorical):
i) John 19:15
ii) Matthew 6:31
e) Rhetorical examples:
i) Mark 8:37
ii) Romans 10:14
