Statement 1 is correct. Subsidiary motions, such as motions to adjourn, close debate, or amend, have no independent meaning and must be connected to a substantive motion. Statement 2 is correct. Kangaroo closure is a procedural device where the presiding officer selects only the most important clauses of a Bill or resolution for discussion and voting, effectively skipping discussion and voting on the less important clauses to save time. Statement 3 is correct. A substantive motion is an independent proposal dealing with a significant matter (like impeachment of the President or Chief Justice, or a vote of no-confidence), requiring a decision by the House. The motion for the removal of the President is a self-contained proposal of great importance.
