click to correct the four capitalization errors. after he retires, my grandfather plans to visit the base of mount everest and take a boat ride down the amazon river.
Answer
Brief Explanations:
- "Grandfather" should not be capitalized as it's a general term (not used as a name).
- "Boat Ride" is not a proper noun and shouldn't be capitalized.
- "river" in "Amazon river" should be capitalized as it's part of the proper noun "Amazon River".
Answer:
After he retires, my grandfather plans to visit the base of Mount Everest and take a boat ride down the Amazon River.
