Error-recognition (and related structure) items ask you to find the part of a sentence that is wrong—or choose the most grammatically acceptable rewrite. On CSE-PPT Verbal Ability, many traps mirror common English habits of Filipino speakers: article use, subject–verb agreement, and prepositions.
How to approach
- Scan for the “usual suspects.” Agreement, tense, articles (*a/an/the*), pronouns, and parallel lists.
- Read the sentence aloud in your head. Awkward rhythm often marks the fault even before you name the rule.
- Test each underlined segment (if any). Mentally replace it; if the sentence improves, you found the error.
- Don’t “correct” style. Prefer clear grammar faults over “I would word this nicer.”
- Watch transfer errors. *In the office yesterday* vs. *yesterday in the office*; *discuss about* vs. *discuss*; *result to* vs. *result in*.
Worked example
Stem: Identify the underlined part that contains an error.
The list of requirements are posted outside Room 3.
- A.The list
- B.of requirements
- C.are
- D.posted outside Room 3
Work: The true subject is *list* (singular), not *requirements*. Singular subject → *is*, not *are*. Answer: C. are.
Common traps
- Nearest-noun agreement — Matching the verb to the object of a preposition (*of the forms*) instead of the head noun.
- Discuss about / request for — Extra prepositions after verbs that already take a direct object.
- Tense freeze — Keeping present tense in a clearly past narrative (*yesterday… arrives*).
- Pronoun drift — *Everyone… their* when the item expects singular consistency (or the reverse, depending on the tested rule).
- False “Filipino English” comfort — Accepting a locally common phrasing that standard exam English still marks wrong.
Quick practice
- Which sentence is structurally best?
- A.The memos was filed by Jun.
- B.The memos were filed by Jun.
- C.The memos were file by Jun.
- D.The memo were filed by Jun.
Answer: B — Plural subject *memos* + past passive *were filed*.
- Spot the error: *She suggested to submit the forms early.* Best correction idea?
Answer: Use *suggested submitting* (or *suggested that we submit*) — *suggest* + gerund/that-clause, not *to* + base verb in this pattern.
