Question

read the excerpt and answer the question.
a student writes this sentence in a report on renewable energy:
\solar panels are good because they make energy from the sun.\
the teacher comments that the sentence is too general and lacks technical accuracy.
which revision best demonstrates the use of precise, domain - specific vocabulary?
photovoltaic cells convert sunlight into electrical energy through processes involving electron excitation in semiconductor materials.
solar panels capture light from the sky and turn it into usable energy for daily consumption.
solar systems gather sunbeams and change them into energy for lighting and heating homes.

Explanation:

The original sentence is too general. The first option uses domain - specific terms like "photovoltaic cells", "electron excitation", and "semiconductor materials" which are precise in the context of renewable energy (solar energy). The second option still has general terms like "usable energy" and "capture light". The third option uses very general and somewhat colloquial terms like "sunbeams" and "change them into energy".

Answer:

Photovoltaic cells convert sunlight into electrical energy through processes involving electron excitation in semiconductor materials.
