Question

click to correct the three capitalization errors. in 1849, elizabeth blackwell received her medical degree from geneva college and became the first female doctor in u.s. history. in 1857, she established a hospital that is known today as the lower manhattan hospital.

Explanation:

1. "Doctor" should be lowercase ("doctor") as it is a common noun here, not a title used as a proper noun in this context.
2. "u.s." should be capitalized to "U.S." as it is the abbreviation for the United States, a proper noun.
3. "Hospital" should be lowercase ("hospital") as it is a common noun here, not a specific, named hospital (the specific name "Lower Manhattan Hospital" is already capitalized correctly).

Answer:

• Change "Doctor" to "doctor"
• Change "u.s." to "U.S."
• Change "Hospital" to "hospital"
