Explanation:

Question 1

In HVACR, distributors of residential and light commercial equipment are typically affiliated with a single equipment brand (franchise or dealership model). Option b is incorrect as they don't own contracting firms. Option c is incorrect as they usually work with contractors, not compete directly. Option d is incorrect as they distribute, not manufacture most products.

Ultraviolet (UV) light is known to kill or inhibit bacteria and harmful organisms. Humidification (b) can promote growth, standard air filters (c) trap particles but not necessarily kill microbes, and cooling (d) alone doesn't eliminate them.

The Office of Apprenticeship at the federal level collaborates with state apprenticeship councils to administer training. Option a: manufacturers’ reps aren't the main collaborators. Option b: local high schools are not the primary partners here. Option c: graduates are not the collaborating entity.

Answer:

a) are usually affiliated with a single equipment brand
