Conjunctions

Why A is correct:
"When" means "at the time that," which makes sense here—you went out at the time that it was raining.

Why the others are wrong:
- B (where): Means "at what place"—doesn't fit because the sentence isn't about location
- C (why): Means "for what reason"—the sentence isn't asking for a reason; it's stating a fact about timing
- D (whose): Shows possession—has nothing to do with the meaning needed here

Correct answer: A (who)

• "Who" is the relative pronoun for people acting as the subject of the clause. Here, "who can speak five languages" describes the woman, and "who" is the subject doing the speaking.

Why the others are wrong:

• B (when) – Used for time, not people. Example: "the day when she arrived."
• C (where) – Used for places, not people. Example: "the city where I live."
• D (whose) – Shows possession ("the woman whose book..."), not the subject of an action.

Correct answer: that
This is a relative clause describing the house. "That" is the correct relative pronoun for things/objects. The clause "that is 100 years old" tells us which house Emma lives in.

Why the others are wrong:
- Why - used for reasons ("the reason why..."), not to describe things
- Whose - shows possession ("the house whose roof..."), but we're just describing the house, not what belongs to it
- Who - only for people, not objects like houses

Correct answer: WHERE

• The sentence needs a location/place word to complete the idea "I go [to a place that adventure calls."
• "Where" is an adverb that answers the question "to what place?" — perfect for "I go where adventure calls."

Why the others don't work:

• What — asks "which thing?" Not asking for a thing here.
• Why — asks for a reason. The sentence structure doesn't fit ("I go why..." doesn't make sense).
• Whose — asks "belonging to whom?" We're not talking about possession here.

Correct Answer: whose
- "Whose" is a possessive relative pronoun used to show that something belongs to someone. Here, the pen belongs to the girl, so "whose" is correct: "She is the girl whose pen I dropped."

Why the others are wrong:
- When – a time connector, not a possessive pronoun; doesn't fit this sentence structure
- Where – a location connector; the sentence isn't about a place
- Whom – an object pronoun used for people, but we need the possessive form "whose" here, not an object form

Why A is correct:
"Where" is an adverb that answers the question "in what place?" The sentence needs to show the location of the incident, so "where" fits perfectly: "This is where the incident took place."

Why the others are wrong:
- B (what) — asks about things/objects, not locations
- C (whom) — is the object form of "who" (a person), not a location word
- D (whose) — shows possession ("belonging to whom"), not a place

Why A is correct:
"Who" is a subject pronoun used for relative clauses. Here, the woman (subject) is performing the action of "wearing," so you need the subject form "who."

Why the others are wrong:
- B (what): Used for things, not people
- C (whose): Shows possession ("the woman whose hat..."), but we're not showing possession here
- D (whom): The object form of "who," but the woman is the subject doing the action, not receiving it

Correct answer: A (who)

• "Who" is a relative pronoun used for people. It introduces a clause describing the man and what he can do.

Why others are wrong:

• B (when) — Used for times/occasions, not people. "When" doesn't make sense here.
• C (where) — Used for places, not people. We need a person pronoun, not a location word.
• D (why) — Used for reasons/causes. It doesn't work grammatically in this sentence structure.

Correct answer: A (that)

You need a relative pronoun to connect "fish" to the description about it. "That" works here because it refers back to the noun "fish" and introduces a relative clause ("that is 20 years old").

Why the others don't work:
- B (why) – Used to ask about reasons, not to describe nouns
- C (whose) – Shows possession (like "the fish whose owner is Emma"), but the sentence describes the fish itself, not what it owns
- D (when) – Used for time, not to describe nouns

Why A is correct:
"When" shows the timing of two events—the ball hitting you caused you to fall, and these happened at the same moment. It's the right time connector here.

Why the others don't work:
- B (where): Shows location, not time. "I fell where the ball hit me" changes the meaning awkwardly.
- C (why): Asks for a reason/explanation. "I fell why the ball hit me" is grammatically broken.
- D (that): Creates a incomplete or awkward structure. "I fell that the ball hit me" isn't standard English for this meaning.
