Key: A

Detailed analysis: A coherent paragraph should begin with a definition, then add supporting details, then move to how it works in practice, and finally give examples of the kinds of issues involved.

Step-by-step coherence:

(3) is the best opening because it defines what a political party is. A definition first \(\gt\) makes the topic clear.

(2) naturally follows by adding a general fact about large parties (members and supporters).

(1) explains the aim/purpose of the party, which logically builds on the definition.

(4) then describes the democratic process (voters choose candidates) which connects to parties supporting different sides.

(5) closes by giving examples of the public-interest questions being debated.

Why other orders are weaker: Options starting with (2) begin with a detail (“large party has millions...”) without defining what a party is, so coherence is \(\lt\) option A.

Key: B

Detailed analysis: The paragraph should follow a realistic timeline: see an ad \(\gt\) decide to apply \(\gt\) contact the company \(\gt\) get an interview schedule \(\gt\) prepare \(\gt\) go to the office \(\gt\) meet the manager \(\gt\) receive the job offer.

Chronological flow check:

(2) comes first: you must see the advertisement before you can apply.

(1) follows: deciding to apply is the natural reaction to seeing the ad.

(4) next: calling to confirm the vacancy is a reasonable next step.

(6) follows: the company tells the applicant to come for an interview the next day.

(5) then: “The next morning...” he gets dressed for the interview.

(3) next: he goes to the address for the interview.

(8) then: he is asked to go into the manageress’s office (interview room).

(7) last: after questions, the manager offers him the job (a closing outcome).

Why other options fail: Option A starts with (1) before (2), which is illogical because you cannot decide to apply before seeing the ad \(\lt\) option B.

Key: D

Detailed analysis: Rita says “Pleased to meet you,” and Don replies similarly. This indicates Jack is introducing Don to Rita. The standard polite introduction is: “I'd like you to meet my friend Don.”

Speech function: Introduction \(\gt\) “I'd like you to meet ...” is the most natural formula.

Option analysis:

A. Don is my friend: incomplete as an introduction; it does not directly address Rita to meet him.

B. Don wants to meet you: gives information but does not perform the introduction.

C. don't you know Don is my friend: impolite/odd and does not match the friendly meeting tone.

D. I'd like you to meet my friend Don: correct and matches the replies.

E. please introduce yourself to Don: tells Rita what to do; less natural than Jack doing the introduction.

Key: B

Detailed analysis: Direct command: “Clean your room!” becomes reported speech with “told + object + to + verb.” Also, the pronoun changes from “your” (addressed to Siscka) to “my” (Siscka reporting it). So: “She told me to clean my room.”

Grammar rule: Command \(\gt\) “told me to + V1” and pronoun shift “your” \(\gt\) “my.”

Option analysis:

A. clean my room: missing “to” after “told me” (ungrammatical).

B. to clean my room: correct structure and correct pronoun.

C. to clean your room: pronoun is wrong; Siscka should say “my room.”

D. cleaned my room: wrong structure; “told” is followed by infinitive, not past tense.

E. clean your room: keeps the original command form, not reported speech.

Key: E

Detailed analysis: The question uses past continuous: “What was your sister doing when you arrived home last night?” This asks about an action in progress at a specific past time. Therefore the answer should also use past continuous: “She was cooking in the kitchen.”

Time pattern: “was ... doing” \(\gt\) past continuous for the ongoing activity; “when you arrived” is the interrupting event.

Option analysis:

A. cooks: simple present, wrong time frame.

B. is cooking: present continuous, wrong time frame.

C. has cooked: present perfect, focuses on completed result, not ongoing past action.

D. has been cooking: present perfect continuous, wrong time frame.

E. was cooking: correct past continuous for an action in progress in the past.
