Read the sentence carefully and choose suitable preposition for the purpose.He…

Answer: through — This is the best choice.

Reason: "through" shows movement via an opening or passage (moving from one side to the other). It fits the sentence describing passing via the gate.

• through: movement via an opening. Example: "He entered through the gate without any difficulty."

• from: indicates origin (where someone came from). Example: "She entered from the back door." It does not emphasize passing through an opening.

• in: often used with time or to indicate location, not for passing through an opening. Example: "She entered this college in 2000."

• into: indicates movement from outside to inside. Example: "He went into the house through the gate." In the given sentence, "through" is the more natural choice to describe passing via the gate.

Corrected sentence: He entered through the gate without any difficulty.
