Explanation:

Question 1

In HVACR distribution, residential and light commercial equipment distributors typically affiliate with a single brand to focus on that brand's products. Option b is incorrect as they don't own contracting firms. Option c is wrong as they don't compete directly with contractors. Option d is incorrect as they don't manufacture most of what they sell.

Ultraviolet (UV) light is known to kill or inhibit bacteria and harmful organisms. Humidification (b) can promote growth, standard air filters (c) don't target organisms directly, and cooling air (d) doesn't eliminate them.

The Office of Apprenticeship works closely with state apprenticeship councils at the federal - state partnership level. Manufacturers' reps (a) aren't the main collaboration, local high schools (b) are not the primary, and apprenticeship graduates (c) are the end - result, not the collaboration partner.

Answer:

a) are usually affiliated with a single equipment brand
