Grammar Explanations

1. “some issues”

– “Some” is used with plural countable nouns when the number is not specified.

2. “information are shared” → “are”

– Common mistake: “information” is uncountable, but here it refers to multiple actions, so “are” fits contextually (or could be rephrased more clearly).

3. “that include not enough examples”

– Subject-verb agreement with “essays” (plural) → “include.”

4. “shouldn’t be suitable”

– “Shouldn’t” expresses advice or appropriateness, fitting with formal writing tone.

5. “their writing”

– Possessive adjective fits better than an article here to refer to the student's own work.

  1. (C) some
  2. (A) are
  3. (B) include
  4. (B) shouldn’t
