Explanation:

Section B (Which Word Does Not Belong?)

1. A barometer measures air pressure (related to weather; weatherglass is a synonym). Storms, pressure, and weatherglass relate to barometer use; judgment does not.
2. Diameter is a straight line across a circle through its center. Center, circle, and square (a shape with diameter-like measurements) relate; distance is a general term not specific to diameter.
3. Optometry is the practice of eye care, linked to eyes, glasses, and eye doctors. Disease is a general health term not directly tied to optometry.
4. Perimeter is the total length around a shape, related to length, distance, and yard (a unit of length). Outside refers to position, not perimeter measurement.
5. Symmetry means matching/balanced parts, linked to mirror-image, same, and equal. Unique means one-of-a-kind, the opposite of symmetric matching.

Section C (Synonyms or Antonyms?)

1. Precaution (a preventive action) and negligence (failure to take care) have opposite meanings.
2. Forecast (predict) and ignore (pay no attention) have opposite meanings.
3. Antebellum (pre-Civil War U.S.) and reconstruction (post-Civil War U.S.) refer to opposite time periods, so they are antonyms.
4. Antecedent (a preceding thing) and precursor (a forerunner) have the same meaning.
