    deposition. If a discovery deposition is desired, it shall

    desposition only.

    reporter's certification shall state the reason for the omission
    of the signature. Copies of the transcripts shall be available to

    any relevant documents described in the request. Copies of the
    documents shall be served with the request unless copies have
    already been furnished.
    b) Each of the matters of fact and the genuineness of each document

    qualification of a matter, the party shall specify the part that
    is true and deny the remainder.
    d) Any objections to a request or to an answer shall be heard by the
