SHORTCUT TRICK - Common Error Spotting:
1. Collective nouns (team, group, family) are usually singular
2. 'One of the + plural noun' always takes singular verb
3. 'Each/Every/Either/Neither' always singular
Formula for Preposition Problems:
Adjective + Preposition combinations:
- Different FROM (not than)
- Superior/Inferior TO (not than)
- Afraid OF (not from)
- Good AT (not in)
Most Common Trap (#1 Student Mistake):
Students often choose the most 'different-looking' option thinking change is always required
