Choose the option that correctly combines the two sentences into one:
Harish fenced his wheat field. He wanted to keep the stray cattle out.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Harish fenced his wheat field so that he could keep the stray cattle out.
The second sentence gives the purpose of the first action. Harish put up the fence to keep the cattle out. A purpose is shown with so that, followed by “could” or “can”.
Why the Other Options are Incorrect?
Option 1: Harish fenced his wheat field although he wanted to keep the stray cattle out. — Incorrect. “Although” shows a contrast. There is no contrast between putting up a fence and wanting to keep cattle out.
Option 2: Harish fenced his wheat field so as he could keep the stray cattle out. — Incorrect. “So as” must be followed by “to” and a verb (“so as to keep”). It cannot take a subject and “could”.
Option 4: Harish fenced his wheat field so that he could not keep the stray cattle out. — Incorrect. The extra “not” turns the aim upside down. Harish wanted the cattle kept out.
