"Human-made climate change and human-made technology can be a key advantage," said Technology Transfem.

Aircraft emissions contribute significantly to humanity's carbon footprint. Computational fluid dynamics programs developed at NASA allow engineers to design an aircraft's shape to minimize drag, allowing for maximal fuel efficiency.

What is the meaning of "drag" as it is used in the excerpt?

A. resistance
B. pulling
C. weight
D. nuisance

Final answer:

In the context, drag refers to the resistance that opposes an aircraft's motion, affecting fuel efficiency.


Explanation:

In the context of the excerpt, drag refers to the resistance that acts opposite to the direction of motion of the aircraft. It is a force that hinders the movement of the aircraft through the air, making it harder to propel forward efficiently. By designing the aircraft's shape to minimize drag, engineers can enhance fuel efficiency by reducing the resistance the aircraft encounters during flight.
