Fairness in applying rules and laws is justice. Justice means treating everyone equally under the rules, enforcing laws impartially, and following due process so outcomes aren’t swayed by who you are or who you know. In a maritime setting, this shows up as applying shipboard and regulatory rules consistently—so a cadet or crew member who breaks a rule faces the same standard consequence as anyone else, and decisions are based on established procedures rather than favoritism. That consistent, unbiased application of rules is what justice is all about. Other traits you might have heard of—loyalty, knowledge, tact—play different roles. Loyalty is allegiance to people or a group, knowledge is understanding rules and procedures, and tact is handling situations with diplomacy. None of these capture the idea of fairness in enforcing rules as clearly as justice does.

An Intramural Officer is the student leader responsible for organizing intramural sports and activities. In the current roster, first-class cadet Landfors is listed as the Intramural Officer, which is why this option is correct. The other names are assigned to different leadership posts, not this role. Roster assignments can change, so checking the latest staff list confirms the current holder.

Stability is about how a vessel behaves when it is tilted and, more importantly, its tendency to return to upright after a disturbance. When the ship heels, the buoyant force shifts and a righting or overturning moment is created. If the center of gravity sits below the metacenter, the buoyancy shift generates a restoring moment that tends to bring the vessel back upright; this restoring capability is governed by the metacentric height (the distance between the center of gravity and the metacenter). A positive GM means a restoring moment exists, so the ship tends to recover after small tilts; a larger GM generally means a stronger righting moment (though it also makes the initial motion feel stiffer). If GM is negative, the vessel becomes unstable and can capsize. That’s why the definition centers on returning upright after a disturbance and why metacentric height is the controlling factor. The other options describe speed maintenance, structural maintenance, or cargo handling rather than the ship’s response to a tilt, so they do not define stability.

The main idea is understanding which sail provides most of the vessel’s power. On a typical two-sail setup, the mainsail is the larger sail attached to the mast and boom, and it delivers the primary source of propulsion. The jib, by contrast, is a triangular sail set forward of the mast on the forestay; it helps with upwind performance and balance but does not usually supply as much power as the mainsail. So the statement that the mainsail is the primary sail correctly captures its dominant role in driving the boat. The other options describe the mainsail as a forward triangular sail or the jib as a large square sail, which don’t match how these sails are arranged or operate.
