1. Identify the error: 'Me and him went to the park.'
ApplyShow Answer →
Answer
Should be 'He and I went to the park' (subject pronouns)
Explanation
Use subject pronouns (I, he, she, we, they) as sentence subjects. Object pronouns (me, him, her, us, them) follow verbs/prepositions. Tip: remove other person and test: 'Me went' sounds wrong, 'I went' sounds right.
Type: multiple choice
2. Which sentence uses commas correctly?
ApplyShow Answer →
Answer
'I bought apples, oranges, and bananas.' (Oxford comma)
Explanation
Use commas to separate items in a series. The Oxford comma (before 'and') prevents ambiguity. Without it, 'I thank my parents, Oprah and God' implies your parents ARE Oprah and God!
Type: multiple choice
3. Choose the correct verb: 'Neither the teacher nor the students ___ ready.'
ApplyShow Answer →
Answer
were (verb agrees with nearest subject)
Explanation
With 'neither...nor,' the verb agrees with the nearest subject (proximity agreement). 'Students' is plural, so use 'were.' If reversed ('neither the students nor the teacher'), use 'was.'
Type: multiple choice
4. True or False: 'Who' is used for subjects, 'whom' for objects.
UnderstandShow Answer →
Answer
True
Explanation
Who = subject (Who called?). Whom = object (To whom did you speak? Whom did you see?). Tip: if you'd answer with 'he,' use 'who'; if 'him,' use 'whom.' 'Whom' is becoming archaic in casual speech.
Type: true false
5. Identify the adverb: 'She sings beautifully.'
RememberShow Answer →
Answer
Beautifully (modifies verb 'sings')
Explanation
Adverbs modify verbs, adjectives, or other adverbs. Many (not all) end in -ly. They answer how, when, where, or to what extent. 'Beautifully' tells HOW she sings.
Type: multiple choice
6. Fix the fragment: 'Because I was tired.'
ApplyShow Answer →
Answer
Add an independent clause: 'Because I was tired, I went to bed.' OR 'I went to bed because I was tired.'
Explanation
Subordinating conjunctions (because, although, if, when, while) create dependent clauses that need an independent clause to complete the sentence. Can't stand alone.
Type: multiple choice
7. Which sentence has correct apostrophe usage?
ApplyShow Answer →
Answer
'The dog's bone' (possessive singular) and 'The dogs' bones' (possessive plural)
Explanation
Apostrophes show possession. Singular: add 's (dog's). Plural ending in s: add only ' (dogs'). Plural not ending in s: add 's (children's). Never use apostrophes for regular plurals.
Type: multiple choice
8. Choose correct: 'Each of the students ___ their own book.' or 'Each of the students ___ his or her own book.'
ApplyShow Answer →
Answer
'Each of the students has his or her own book.' OR 'All students have their own books.' (avoid singular they with 'each')
Explanation
'Each' is singular, so use 'has.' Traditionally 'his or her' for singular, but modern usage increasingly accepts singular 'they/their.' Rewrite to plural avoids issue.
Type: multiple choice
9. Identify the misplaced modifier: 'She served sandwiches to the children on paper plates.'
AnalyzeShow Answer →
Answer
Sounds like children were on plates. Fix: 'She served sandwiches on paper plates to the children.'
Explanation
Misplaced modifiers create confusion or unintended humor. Place modifiers next to what they modify. 'On paper plates' modifies 'sandwiches,' not 'children.'
Type: multiple choice
10. True or False: 'Good' is an adjective, 'well' is an adverb.
UnderstandShow Answer →
Answer
True (with exception: 'well' can be adjective meaning healthy)
Explanation
True. Good modifies nouns (good book). Well modifies verbs (sings well). Exception: 'I feel well' (healthy). But: 'I feel good' (happy/satisfied). Common error: 'She did good' should be 'She did well.'
Type: true false
11. Which is correct: 'Less people' or 'Fewer people'?
ApplyShow Answer →
Answer
'Fewer people' (countable)
Explanation
Use 'fewer' with countable nouns (fewer people, fewer books). Use 'less' with uncountable nouns (less water, less time). Common error: 'less items' should be 'fewer items.'
Type: multiple choice
12. Fix the run-on: 'I love grammar it's fascinating.'
ApplyShow Answer →
Answer
Options: (1) 'I love grammar. It's fascinating.' (2) 'I love grammar; it's fascinating.' (3) 'I love grammar, and it's fascinating.'
Explanation
Run-on sentences improperly join independent clauses. Fix with: (1) period, (2) semicolon, (3) comma + coordinating conjunction (FANBOYS: for, and, nor, but, or, yet, so), or (4) subordination.
Type: multiple choice
