Answer 1

Step-by-step explanation:

The statement that best indicates that the primary audience is academics in the field of engineering is:

"The writer uses specialized language such as drag, thrust, and apogee point."

These terms (drag, thrust, and apogee point) are technical engineering terms that are specific to the field, and their use suggests that the content is intended for an audience with expertise in engineering.
