A number of sailors manning a ship

This question is asking about the term used to describe a group of sailors who work on a ship. The options given are crew, gang, staff, and host.

The correct answer is Option A: crew.

A crew refers to a group of people who work together on a ship, especially sailors. They perform various tasks and duties to ensure the smooth operation and navigation of the ship. This includes tasks like steering the ship, maintaining the equipment, and performing other necessary functions.

The term "gang" is often used to describe a group of people involved in criminal activities, so it is not the correct answer in this case.

"Staff" typically refers to a group of people who work in an organization or business, but it may not specifically refer to sailors on a ship.

"Host" usually refers to someone who welcomes and entertains guests, which is not the correct term for sailors on a ship.

Therefore, the correct answer to this question is Option A: crew, as it accurately describes the group of sailors who work on a ship.
