Question

read the excerpt
the engineer adjusted the circuit, careful to calibrate each resistor to exact specifications. any deviation could trigger a catastrophic failure.
which statements are true about the words and their impact on meaning and tone? (select all that apply)
a the word \calibrate\ is a technical term specific to engineering.
b \catastrophic failure\ carries a strong negative connotation, emphasizing risk.
c the language creates a tense and serious tone.
d the phrase \careful to calibrate\ is figurative because it exaggerates the engineers precision.

Explanation:

• Option A: "Calibrate" is indeed a technical term commonly used in engineering (e.g., calibrating instruments, circuits).
• Option B: "Catastrophic failure" has a strong negative connotation as it implies a very bad outcome (failure) of a severe nature (catastrophic), emphasizing risk.
• Option C: The mention of needing to be careful (to avoid a catastrophic failure) creates a tense and serious tone.
• Option D: "Careful to calibrate" is not figurative. It is a literal description of the engineer's action (being precise in calibration).

Answer:

A. The word "calibrate" is a technical term specific to engineering.
B. "Catastrophic failure" carries a strong negative connotation, emphasizing risk.
C. The language creates a tense and serious tone.
