All questions
Question 1
Which relative pronoun should fill the blank: "The boy backpack is green is Jamal"?
- whose (correct answer)
- who
- where
- which
Explanation: This question tests CCSS.L.4.1.a: using relative pronouns (who, whose, whom, which, that) and relative adverbs (where, when, why) correctly. Students must choose the appropriate relative word based on what it refers to. Relative pronouns connect information about people or things: WHO for people doing actions, WHOSE for possession, WHICH or THAT for things or animals. The correct choice depends on whether you're adding information about a person, thing, place, time, or reason. In this sentence, the relative pronoun connects information about possession - specifically, whose backpack belongs to whom. The sentence is describing a boy and identifying him by his green backpack. Choice A (whose) is correct because WHOSE shows possession and connects information about who owns the backpack. We use WHOSE when connecting a clause about possession or ownership, which is exactly what this sentence needs. Choice B (who) represents confusing subject pronouns with possessive pronouns, which occurs when students don't distinguish between pronouns for people doing actions versus showing ownership. Using 'who' doesn't work because it refers to people performing actions, not showing possession. To help students: Teach simple rules - WHO for people, WHICH/THAT for things, WHERE for places, WHEN for times, WHY for reasons, WHOSE for possession. Create anchor chart with examples like 'The girl WHOSE book is red' vs 'The girl WHO reads books'. Practice identifying whether the pronoun shows action or possession. Watch for: confusing WHO (subject) and WHOSE (possessive), using WHERE for possession, forgetting that WHOSE shows ownership. Have students ask 'Does this show who owns something?' to check for WHOSE.
Question 2
Which word correctly completes: "I know a girl can sing very well"?
- which
- whose
- who (correct answer)
- when
Explanation: This question tests CCSS.L.4.1.a: using relative pronouns (who, whose, whom, which, that) and relative adverbs (where, when, why) correctly. Students must choose the appropriate relative word based on what it refers to. Relative pronouns connect information about people or things: WHO for people doing actions, WHOSE for possession, WHICH or THAT for things or animals. The correct choice depends on whether you're adding information about a person, thing, place, time, or reason. In this sentence, the relative pronoun connects information about a person (a girl) who can perform an action (sing). The sentence is describing a girl by telling what she can do. Choice C (who) is correct because WHO refers to the person who is doing the action of singing. We use WHO when connecting a clause about a person performing an action, which is exactly what this sentence needs. Choice A (which) represents using a thing pronoun for a person, which occurs when students don't distinguish between pronouns for people versus things. Using 'which' doesn't work because WHICH is for things or animals, not people. To help students: Teach simple rules - WHO for people, WHICH/THAT for things, WHERE for places, WHEN for times, WHY for reasons, WHOSE for possession. Create anchor chart with examples: 'The boy WHO plays', 'The dog WHICH barks'. Practice identifying whether the pronoun refers to a person or thing before choosing. Watch for: using WHICH for people, confusing WHO (subject) and WHOSE (possessive), using WHEN for people. Have students replace relative pronoun with what it refers to to check ('A girl WHO can sing' → 'A girl - she can sing').
Question 3
Which word best joins these clauses: "This is the park we practice soccer"?
- when
- where (correct answer)
- who
- that
Explanation: This question tests CCSS.L.4.1.a: using relative pronouns (who, whose, whom, which, that) and relative adverbs (where, when, why) correctly. Students must choose the appropriate relative word based on what it refers to. Relative adverbs connect information about places (WHERE), times (WHEN), or reasons (WHY), while relative pronouns connect information about people or things. The correct choice depends on whether you're adding information about a person, thing, place, time, or reason. In this sentence, the relative adverb connects information about a place (the park) where an activity happens. The sentence is describing a specific park by telling what happens there. Choice B (where) is correct because WHERE connects information about the place where we practice soccer. We use WHERE when connecting a clause about a location or place, which is exactly what this sentence needs. Choice D (that) represents using a relative pronoun instead of a relative adverb, which occurs when students don't recognize that the sentence is describing a place. Using 'that' could work grammatically but 'where' is more precise for places. To help students: Teach simple rules - WHO for people, WHICH/THAT for things, WHERE for places, WHEN for times, WHY for reasons, WHOSE for possession. Create anchor chart with place examples: 'The school WHERE we learn', 'The store WHERE Mom shops'. Practice asking 'Is this about a place, time, or reason?' For sentence combining, ask 'What am I adding information about - a person, thing, place, time, or reason?' Watch for: using WHEN for places, using WHO for places, or defaulting to THAT for everything. Have students test by asking 'Can I say AT/IN this place?' - if yes, use WHERE.
Question 4
Which relative pronoun should fill the blank? "The book I need is on Ms. Chen's desk."
- who
- where
- that (correct answer)
- when
Explanation: This question tests CCSS.L.4.1.a: using relative pronouns (who, whose, whom, which, that) and relative adverbs (where, when, why) correctly. Students must choose the appropriate relative word based on what it refers to. Relative pronouns connect information about people or things: WHO for people, WHICH or THAT for things or animals. THAT is especially common for things when the information is essential to identify which specific thing we mean. In this sentence, the relative pronoun connects information about a thing (the book) that the speaker needs. The sentence is identifying which specific book by describing it as the one needed, and we need a word that refers to a thing. Choice C (that) is correct because THAT refers to the thing (book) and introduces essential information identifying which book. We use THAT when connecting a clause about things with necessary identifying information, which is exactly what this sentence needs. Choice A (who) represents using a person pronoun for a thing, which occurs when students apply WHO too broadly or don't distinguish between pronouns for people vs things. Using WHO doesn't work because WHO is only for people, not objects like books. To help students: Teach simple rules - WHO for people, WHICH/THAT for things, with THAT being very common for essential information. Create anchor chart with examples like 'The book THAT I read' vs 'The girl WHO reads.' Practice identifying whether the pronoun refers to a person or thing before choosing. Watch for: using WHO for things, confusion between WHICH and THAT (both work for things), forgetting that books are things not people. Have students replace the pronoun to check ('The book THAT I need' → 'The book - I need it').
Question 5
Which word correctly completes: "The student won the art contest is Keisha"?
- which
- where
- who (correct answer)
- whose
Explanation: The blank connects extra information about a person, the student, who did something (won the art contest). The word "who" is used for people who are doing an action, so it is the correct choice. "Which" is used for things or animals, not for people, so it does not fit a sentence about a student. "Where" is used for places, like a room or a city, but the blank is not talking about a place. "Whose" is used to show that something belongs to a person, such as "the student whose painting won," but here the student is the one doing the action, not owning something. A good trick is to replace the word with the person: "The student who won" becomes "she won," which makes sense. Because the sentence needs a word that links a person to an action, "who" is the only word that works.
Question 6
Which word connects these ideas correctly? "Carlos brought his bike, is blue."
- that
- which (correct answer)
- who
- whose
Explanation: The blank needs a word that adds extra information about a thing, the bike, after a comma. "Which" is the right choice because it refers to things and is used after a comma to add details that aren't essential, like the bike being blue. "That" also refers to things, but it is used without a comma to give needed information, not extra information after a comma, so it doesn't fit here. "Who" refers to people, not objects, so it can't describe a bike. "Whose" shows possession, meaning something belongs to someone, but here the sentence isn't showing ownership—it's just telling the bike's color. A helpful trick: replace the word with what it points to. "His bike, it is blue" works, so you need the thing word that follows a comma: which.
Question 7
Which word should replace where to fix this sentence: "The time where we eat is noon"?
- when (correct answer)
- why
- which
- who
Explanation: The sentence is describing 'the time' that something happens, so it needs a relative adverb that connects information about time. 'When' is the word we use to talk about a time or moment, so it fixes the sentence: 'The time when we eat is noon.' 'Where' was wrong because it points to a place, not a time. 'Why' is also a relative adverb, but it points to a reason, not a time, so it does not match 'the time.' 'Which' points to a thing, and here we are naming a time, not a thing. 'Who' points to a person, and 'the time' is not a person. To pick the right word, look at what you are describing—a time signals 'when,' a place signals 'where,' and a reason signals 'why.'
Question 8
Which relative pronoun should fill the blank? "The girl backpack is purple is Sofia."
- whose (correct answer)
- who
- that
- which
Explanation: The blank needs a word that shows the backpack belongs to the girl. "Whose" is the relative pronoun for possession, so it correctly connects the girl to something she owns. "Who" is used for a person doing an action, like "The girl who runs fast," but here nobody is doing an action, so it does not fit. "That" points to a thing or animal, not to the person the backpack belongs to, so it cannot show the girl's ownership. "Which" also refers to things, and it would need a comma and no possession, so it does not show that the backpack is the girl's. A quick test: try adding "belongs to her." "The girl — the backpack belongs to her" matches "whose," which is why it is the best choice.
Question 9
Which word correctly completes the sentence? "The place Carlos studies each afternoon is that quiet room by the window."
- where (correct answer)
- why
- who
- whose
Explanation: The sentence names a spot—the quiet room by the window—where Carlos does something. The word "where" connects a clause to a place, so it fits perfectly here. "Why" is used to point back to a reason for something, but this sentence is not explaining a reason, so it does not fit. "Who" is used to point back to a person, and here the missing word connects to a place, not a person, so it is wrong. "Whose" shows that something belongs to someone, but nothing in this sentence is being owned, so it does not work either. Only "where" correctly links the room to what Carlos does there.
Question 10
Which word correctly completes the sentence? "The teacher helps Jamal with math is Mr. Chen."
- which
- who (correct answer)
- where
- whose
Explanation: The blank needs a relative word that connects information about a person, the teacher. "Who" is correct because we use it for a person who is doing an action, and the teacher is the one helping Jamal. "Which" is wrong because we use it for things or animals, not for people. "Where" is wrong because it points to a place, but the sentence is talking about a person, not a location. "Whose" is wrong because it shows that someone owns something, like "the teacher whose desk is messy," but here nothing belongs to the teacher—the teacher is doing the helping. A quick trick: try replacing the relative word with what it stands for. "The teacher who helps Jamal" becomes "He helps Jamal," which makes sense, so "who" is the best choice.
Question 11
Which word correctly completes the sentence? "The student found the lost lunchbox is Jamal."
- which
- whom
- who (correct answer)
- whose
Explanation: The blank needs a relative pronoun that stands for a person doing an action. In this sentence, the student is the one who found the lunchbox, so we need the word that acts as the subject of that action. "Who" is correct because it refers to a person who is doing something. "Whom" also refers to a person, but it is used as an object, not as the subject doing the action, so it does not fit here. "Whose" shows that a person owns something, but the student does not own the finding, so it is wrong. "Which" refers to things or animals, not people, so it cannot describe the student. A quick check: try replacing the blank word with "he" — "the student, he found the lunchbox" — and the subject word that matches "he" is who.
Question 12
Which word correctly completes the sentence? "Keisha is the student won the art contest."
- where
- who (correct answer)
- whose
- which
Explanation: This sentence adds information about a person, Keisha, and tells what she did: she won the art contest. The word "who" is the right choice because we use "who" to connect a clause about a person who is doing an action. "Whose" is wrong because it shows possession, like something a person owns, but here Keisha is not owning anything—she is doing an action. "Which" is wrong because we use it for things or animals, not for a person. "Where" is wrong because it points to a place, and Keisha is a person, not a place. Tip: replace the missing word with the person it stands for. "The student—she won the art contest" shows you need "who," the word that stands for a person doing something.
Question 13
Which word correctly completes the sentence? "The reason Carlos is smiling is his good grade."
- why (correct answer)
- when
- which
- whose
Explanation: The word "why" fits after "the reason" because it points to the cause or explanation for something — here, why Carlos is smiling. "When" tells about a time, not a reason, so it does not match "the reason." "Which" points back to a thing you are choosing or describing, not to a reason, so the sentence would not make sense. "Whose" shows that something belongs to someone, so it needs a person and a possession, which this sentence is not talking about. Only "why" correctly connects "the reason" to the explanation that follows.
Question 14
Which word best joins these clauses? "The reason Maya stayed home was a fever."
- where
- why (correct answer)
- who
- which
Explanation: This question tests CCSS.L.4.1.a: using relative pronouns (who, whose, whom, which, that) and relative adverbs (where, when, why) correctly. Students must choose the appropriate relative word based on what it refers to. Relative pronouns connect information about people or things, while relative adverbs connect information about places (WHERE), times (WHEN), or reasons (WHY). The correct choice depends on whether you're adding information about a person, thing, place, time, or reason. In this sentence, the relative adverb connects information about a reason - explaining why Maya stayed home. The sentence is providing an explanation or cause, and we need a word that refers to a reason. Choice B (why) is correct because WHY connects information about the reason or cause for staying home. We use WHY when connecting a clause that explains a reason, which is exactly what this sentence needs after 'The reason.' Choice A (where) represents confusing reason with place, which occurs when students focus on concrete concepts (places) rather than abstract ones (reasons). Using WHERE doesn't work because WHERE refers to places, not reasons or explanations. To help students: Teach simple rules - WHERE for places, WHEN for times, WHY for reasons. Create anchor chart with examples like 'The reason WHY she left' vs 'The place WHERE she went.' Practice identifying reason words (reason, cause, explanation) as signals for WHY. Watch for: using WHERE or WHEN instead of WHY, forgetting that 'the reason' signals WHY, difficulty with abstract concept of reasons. Have students test by asking 'For what reason?' ('The reason WHY Maya stayed home' → 'For what reason did Maya stay home? Because of a fever').
Question 15
Which relative pronoun should fill the blank? "The student won the race is Jamal."
- which
- who (correct answer)
- whom
- whose
Explanation: The blank needs a word that stands for the student and does the action of winning the race. "Who" is right because it refers to a person who is doing something in the sentence: the student who won. You can check it by saying "the student — he won the race." "Whom" also refers to a person, but you use it when the person receives the action, not when the person does it; here the student is the one doing the winning, so "whom" does not fit. "Whose" shows that something belongs to someone, like "the student whose bike is red," but nothing is being owned in this sentence. "Which" is used for things or animals, not for people, so it cannot point back to the student. Only "who" matches a person doing an action, so it is the one best answer.
Question 16
How should these sentences be combined? "I know a teacher. He helps Amir."
- I know a teacher that Amir helps.
- I know a teacher who helps Amir. (correct answer)
- I know a teacher whose class helps Amir.
- I know a teacher which helps Amir.
Explanation: The two sentences are about a person, the teacher, and the teacher is doing something: he helps Amir. To combine them, replace "He" with a relative pronoun that fits a person acting as the subject. "Who helps Amir" is correct because "who" refers to a person who is doing the action of helping. "That Amir helps" changes the meaning: it now says Amir helps the teacher, which is the opposite of the original sentence. "Whose class helps Amir" uses "whose" to show possession, so it says the teacher's class does the helping, not the teacher, which also changes the meaning. "Which helps Amir" is wrong because "which" is used for things, not for people like a teacher. Check your answer by turning it back into two sentences: "I know a teacher who helps Amir" becomes "I know a teacher. He helps Amir." — exactly what we started with.
Question 17
Which word should replace the underlined word? "The park when we play soccer is behind the school."
- where (correct answer)
- when
- why
- which
Explanation: This question tests CCSS.L.4.1.a: using relative pronouns (who, whose, whom, which, that) and relative adverbs (where, when, why) correctly. Students must choose the appropriate relative word based on what it refers to. Relative pronouns connect information about people or things: WHO for people doing actions, WHOSE for possession, WHICH or THAT for things or animals. Relative adverbs connect information about places (WHERE), times (WHEN), or reasons (WHY). The correct choice depends on whether you're adding information about a person, thing, place, time, or reason. In this sentence, the relative adverb connects information about a place, the park, where soccer is played. The sentence is describing the park's location and activity, and we need to replace 'when' with a word that refers to a place. Choice A is correct because WHERE connects information about the place. We use WHERE when connecting a clause about a location, which is exactly what this sentence needs. Choice B represents using the wrong adverb for place vs time, which occurs when students confuse time and place. Using WHEN doesn't work because when refers to times not places. To help students: Teach simple rules - WHO for people, WHICH/THAT for things, WHERE for places, WHEN for times, WHY for reasons, WHOSE for possession. Create anchor chart with examples. Practice identifying what the pronoun/adverb refers to before choosing. For sentence combining, ask 'What am I adding information about - a person, thing, place, time, or reason?' Watch for: using WHICH for people, confusing WHO (subject) and WHOSE (possessive), mixing up WHERE (place) and WHEN (time), forgetting that THAT works for things with essential information. Have students replace relative pronoun with what it refers to to check ('The girl WHO won' → 'The girl - she won').
Question 18
Which word correctly completes the sentence? "Do you remember the day we met Mr. Chen?"
- where
- whose
- when (correct answer)
- which
Explanation: When is used to talk about time, and day refers to a point in time, so when fits correctly here. Where is used for a place, but day is not a place, so it does not fit. Whose shows ownership, which does not match the meaning of this sentence. Which is used to point out one of several things, and it does not fit smoothly into this sentence about time.
Question 19
Which word correctly completes the sentence? "This is the library Maya checks out books."
- when
- where (correct answer)
- who
- that
Explanation: This question tests CCSS.L.4.1.a: using relative pronouns (who, whose, whom, which, that) and relative adverbs (where, when, why) correctly. Students must choose the appropriate relative word based on what it refers to. Relative pronouns connect information about people or things: WHO for people doing actions, WHOSE for possession, WHICH or THAT for things or animals. Relative adverbs connect information about places (WHERE), times (WHEN), or reasons (WHY). The correct choice depends on whether you're adding information about a person, thing, place, time, or reason. In this sentence, the relative adverb connects information about a place, the library, where the action happens. The sentence is identifying the library as the location for checking out books, and we need a word that refers to a place. Choice B is correct because WHERE connects information about the place. We use WHERE when connecting a clause about a location, which is exactly what this sentence needs. Choice A represents confusing time with place, which occurs when students mix up adverb types. Using WHEN doesn't work because when refers to times not places. To help students: Teach simple rules - WHO for people, WHICH/THAT for things, WHERE for places, WHEN for times, WHY for reasons, WHOSE for possession. Create anchor chart with examples. Practice identifying what the pronoun/adverb refers to before choosing. For sentence combining, ask 'What am I adding information about - a person, thing, place, time, or reason?' Watch for: using WHICH for people, confusing WHO (subject) and WHOSE (possessive), mixing up WHERE (place) and WHEN (time), forgetting that THAT works for things with essential information. Have students replace relative pronoun with what it refers to to check ('The girl WHO won' → 'The girl - she won').
Question 20
Which word correctly completes the sentence? "The student won the art contest is Sofia."
- which
- who (correct answer)
- where
- whose
Explanation: The blank connects extra information about a person, the student, who did the action of winning the art contest. The word "who" is right because we use it to point to a person who is the subject doing an action. "Whose" is also for people, but it shows possession, like "the student whose painting won"; here the student is not owning anything, so it does not fit. "Which" is used for things or animals, not for people, so it cannot describe a student. "Where" points to a place, like "the room where we painted," but the blank is describing a person, not telling where something happened. A good trick is to replace the word with what it stands for: "The student who won" becomes "she won" and makes sense, so "who" is the best choice.
