1.	The ________________ plays an important role in the comfort of persons affected by ventilation system.(a) Carbon monoxide(b) Purity of air(c) Volume of room(d) Health of occupantI have been asked this question during an internship interview.I need to ask this question from Types of Ventilation in division Acoustics and Ventilation of Construction & Building Materials
Answer» Correct option is (b) Purity of air To EXPLAIN I would say: The air should be free from odours, organic matter, inorganic DUST and unhealthy fumes of gases such as carbon monoxide, carbon dioxide and Sulphur Dioxide, etc. All the above impurities depend on the habits of occupants, VOLUME of a room, SOURCE of ventilating air, etc.
