English grammar error-spotting (article with number + unit; preposition with ‘‘within’’): Identify the erroneous part in the sentence: ‘‘The school is / within hundred yards / from the church. / No error.’’ Consider article use before countable units and the correct preposition collocating with ‘‘within’’ when expressing distance.

Given data

• A: ‘‘The school is’’
• B: ‘‘within hundred yards’’
• C: ‘‘from the church.’’
• D: ‘‘No error.’’

Concept / ApproachUse an article before singular countable units in measure phrases and prefer ‘‘of’’ after ‘‘within’’ when specifying a distance limit.

Step-by-step evaluationCorrect phrasing → ‘‘within a hundred yards of the church’’.Thus, Part B is erroneous: ‘‘within hundred yards’’.

Correction‘‘The school is within a hundred yards of the church.’’

Common pitfalls

• Omitting articles in fixed measure phrases.
• Using ‘‘from’’ where ‘‘of’’ is idiomatic with ‘‘within’’ + distance limit.

Final Answerwithin hundred yards
