Concept: HVAC dampers are critical components in heating, ventilation, and air-conditioning systems. They are used to regulate and redirect airflow within ducts and can be controlled manually or automatically to maintain desired room temperatures or zone conditions.
Explanation: Dampers work by opening, closing, or modulating positions to control the volume of air passing through a duct. In zone-based HVAC systems, each zone may have different temperature requirements, and dampers ensure that each area receives the appropriate amount of conditioned air.
Correct Description: (A) HVAC dampers regulate the airflow in response to the zone's air conditioning requirements.
Conclusion: ✅ Correct Answer: (A). HVAC dampers regulate the airflow in response to the zone's air conditioning requirements.

A four-arm uncontrolled un-signaled urban intersection of both-way traffic is illustrated in the figure. Vehicles approaching the intersection from the directions A, B, C, and D can move to either left, right, or continue in straight direction. No U-turn is allowed. In the given situation, the maximum number of vehicular crossing conflict points for this intersection is _________ (answer in integer)
An individual chooses a transport mode for a particular trip based on three attributes i.e., cost of journey (X), In-vehicle travel time to reach destination (Y), and Out-of-vehicle time taken to access mode at respective stops (Z). The values for these attributes for three modes Rail, Bus and Para-transit are given in the table. If the general utility (U) equation is \( U = - 0.5 \times X - 0.3 \times Y - 0.4 \times Z \), using the Logit model, the estimated probability of choosing Bus is _________ (rounded off to two decimal places).
