In this question, we are asked to identify the grammatically incorrect sentence. Let’s examine each option:
- Option (1): "The hardy colonist and the trained European who fought at his side,"
This sentence is grammatically correct. It refers to two subjects, "the hardy colonist" and "the trained European," who fought together.
- Option (2): "frequently expended months in struggling against the rapid of the streams,"
This sentence is grammatically incorrect. The phrase "the rapid of the streams" is not correct; the proper expression should be "the rapids of the streams," as "rapids" refers to fast-moving sections of a river or stream. Therefore, this sentence contains an error in the use of the word "rapid."
- Option (3): "or in effecting the rugged passes of the mountains,"
This sentence is grammatically correct. It correctly uses "effecting" to indicate the action of overcoming or achieving something (in this case, the rugged passes).
- Option (4): "in quest of an opportunity to exhibit their courage in a more martial conflict."
This sentence is grammatically correct. It conveys the idea of searching for an opportunity to show bravery in a more martial (war-like) situation.
The grammatically incorrect sentence is Option (2), as it misuses the word "rapid" instead of the correct "rapids."
