1. According to the passage, what is the central claim of the "democratic peace thesis"?
Correct: B — Democracies almost never go to war with one another.
Why B is correct: Paragraph 1 states the claim almost word-for-word: "democracies almost never go to war with one another." The phrase "with one another" is the key — the claim is about democracy-to-democracy relations, not democracy-to-anyone relations.
Why the other options fail:
- A says "never go to war for any reason" — too absolute. The passage explicitly mentions democracies fighting non-democracies.
- C talks about autocracies being aggressive — the passage doesn't make this claim about autocracies in general.
- D says democracy "automatically" produces peace — this is exactly the view the author argues against in the last paragraph.
Strategy tip · Avoiding the "absolute word" trap
Words like never, always, automatically, only in answer choices are often wrong on TOEFL/SAT/GRE. The author of an academic passage rarely makes absolute claims. คำว่า never/always/automatic/only ในตัวเลือกมักเป็นกับดัก — บทความวิชาการมักไม่กล้าพูดเด็ดขาด
2. Which is NOT mentioned as a supporter's reason?
Correct: D — Democratic militaries are technologically more advanced.
Why D is correct: Paragraph 2 lists exactly three supporter reasons: (1) accountability to voters, (2) public negotiation through institutions, (3) exposure to diverse perspectives. Technological advancement is never mentioned.
Why the other options are mentioned:
- A matches "voters... prefer the costs of compromise to the costs of war."
- B matches "negotiate publicly through institutions such as parliaments and free media."
- C matches "citizens... are exposed to diverse perspectives."
Strategy tip · NOT questions
For "NOT mentioned" questions, find evidence for the three options that ARE mentioned. The remaining one is your answer. Going in this direction is faster than trying to prove the negative. โจทย์ NOT — ให้หาหลักฐานของ 3 ข้อที่ "ใช่" จะง่ายกว่าพยายามพิสูจน์ข้อที่ "ไม่ใช่"
3. What is the author implying with "the peaceful behaviour, if it exists, seems to apply only to mature democratic states..."?
Correct: B — The thesis applies in a narrower way than supporters often suggest.
Why B is correct: Two phrases do the work here: "if it exists" expresses doubt, and "only to mature democratic states behaving toward each other" restricts the scope. Together they narrow the original claim — exactly choice B.
Why the other options fail:
- A contradicts "if it exists" — the author is expressing doubt, not full proof.
- C is a moral judgement ("should not be supported") the author never makes.
- D is an absolute claim about age that the author doesn't make.
Strategy tip · Inference = combining clues
Inference questions ask what the author implies, not what is directly stated. Watch for hedge words ("if", "seems", "appears") and scope-limiting words ("only", "mature", "to each other"). These are where authors hide their real position. คำถาม inference — ให้สังเกตคำที่ทำให้ความหมายอ่อนลง (if/seems/appears) และคำที่จำกัดขอบเขต (only/mature)
4. The reference to Britain, France, and the U.S. invading smaller states most likely serves to:
Correct: C — complicate the supporters' optimistic claim with counter-evidence.
Why C is correct: This is a "function" question — it asks why the author included the example, not what the example says. The example sits in paragraph 3, which opens "Critics, however, argue that the picture is more nuanced." So the example's function is to support the critics, who are complicating the supporters' claim.
Why the other options fail:
- A "praise for bravery" — the author's tone is critical, not admiring.
- B "democracy is failed" — far too extreme; the author keeps qualified value in democracy.
- D "wars are morally necessary" — the author never makes this argument.
Strategy tip · "Function" questions
When asked why an author included a detail, ignore the detail itself and look at the paragraph's topic sentence. The detail is doing the work of supporting that paragraph's main move. โจทย์ "ทำไมผู้เขียนยกตัวอย่างนี้" — ให้ดู topic sentence ของย่อหน้านั้น ตัวอย่างคือเครื่องมือ ไม่ใช่จุดหมาย
5. What can be inferred about the author's view of elections and democracy?
Correct: C — Elections alone do not guarantee that a country is truly democratic.
Why C is correct: Paragraph 4 says: "A country may hold elections while severely restricting press freedom, suppressing minorities..." The clear implication is that elections are not enough. The final paragraph reinforces this by listing what real democracy requires: "genuine elections, an independent judiciary, free press, and protected rights."
Why the other options fail:
- A is the OPPOSITE of the author's point. This is a classic trap — the option states what some people believe, but the author is criticising that belief.
- B over-corrects: the author never says elections are "unimportant" — just insufficient.
- D is absurd and not supported anywhere.
Strategy tip · The "opposite" trap
Choice A in this question demonstrates one of the most common tricks: present a view the author is criticising as if it were the author's own view. Always ask: "Whose view is this — the author's, or someone the author is arguing against?" กับดักคลาสสิก — เอาสิ่งที่ผู้เขียน "วิจารณ์" มาเสนอเหมือนเป็นความเห็นของผู้เขียนเอง
6. The word "nuanced" in paragraph 3 most nearly means:
Correct: A — complicated by important subtleties.
Why A is correct: "Nuanced" contrasts with the supporters' simple picture. Paragraph 3 then gives detailed sub-cases (democracies fighting non-democracies; young vs. mature democracies). These details = "subtleties." The contrast structure tells you the meaning.
Why the other options fail:
- B "obviously wrong" — too strong; critics are not saying the thesis is false, only more complicated.
- C "emotionally biased" — has nothing to do with nuance.
- D "entirely new" — irrelevant.
Strategy tip · Use the surrounding contrast
For vocabulary-in-context questions, don't recall the dictionary definition — look at what the word is being contrasted with. Here, "nuanced" sits against the supporters' confident, simple claim. The opposite of "simple and confident" is "complicated with subtleties." โจทย์ความหมายในบริบท — ห้ามใช้นิยามจาก dictionary ในหัว ให้ดูว่าคำนี้ถูกวางตรงข้ามกับอะไรในประโยคแวดล้อม
7. The phrase "the product not of slogans but of patient and sometimes uncomfortable practice" suggests peace is:
Correct: C — built through slow, difficult, ongoing work rather than simple statements.
Why C is correct: The sentence uses the "not X but Y" structure — a classic English contrast. "Not slogans (= simple statements)" "but patient practice (= slow, difficult, ongoing work)." Option C is a direct paraphrase.
Why the other options fail:
- A reverses the meaning — it says peace IS produced by speeches, but the author says it is NOT.
- B twists "uncomfortable" into "warfare," but "uncomfortable practice" refers to compromise, difficult negotiation, etc., not war.
- D "impossible" — far too pessimistic; the author is offering a path to peace, not denying it.
Strategy tip · "Not X but Y" structure
English speakers use "not A but B" to reject one idea and assert another. Whenever you see it, the right answer paraphrases B and matches its contrast with A. โครงสร้าง "not A but B" — ตัวเลือกถูกต้องคือคำที่ตรงกับ B และต้องแสดงความต่างกับ A อย่างชัดเจน
8. Which best describes the author's overall position?
Correct: C — Finds partial value in the thesis but insists on important conditions and limits.
Why C is correct: The author neither dismisses nor endorses the thesis. The final paragraph says democracy "does appear to correlate with restraint" (partial endorsement) but "is not an automatic peace machine" (limit). This is the textbook profile of a balanced academic argument.
Why the other options fail:
- A "without reservation" — the entire paragraph 3 is reservations.
- B "completely rejects" — the author explicitly says the thesis has value when democracy is "properly understood."
- D "refuses to take any position" — false; the author clearly states a qualified position.
Strategy tip · Most academic authors live in the middle
On TOEFL/SAT/GRE, extreme answer choices (fully supports / completely rejects / no position at all) are usually wrong. The right answer typically describes a balanced, qualified position. ผู้เขียนวิชาการส่วนใหญ่อยู่ตรงกลาง — ตัวเลือกที่สุดโต่ง (สนับสนุนเต็มที่/ปฏิเสธสิ้นเชิง/ไม่มีจุดยืน) มักผิด
9. The primary purpose of paragraph 4 is to:
Correct: B — question what "democracy" actually means before we accept any claim about its effects.
Why B is correct: Paragraph 4 opens with "There is a deeper question as well" — signalling that the author is shifting from "do democracies cause peace?" to a more fundamental question: "what counts as democracy in the first place?" The paragraph then describes flawed states that hold elections without being truly democratic.
Why the other options fail:
- A — no new historical example is added; the focus is on a definitional problem.
- C — the author never recommends a specific system for "all countries."
- D — no specific countries are named in this paragraph.
Strategy tip · Paragraph openers are signposts
Phrases like "There is a deeper question," "However," "On the other hand," "What can fairly be concluded" tell you the function of the next paragraph before you read it. Read paragraph openers as roadsigns. คำเปิดย่อหน้าคือป้ายบอกทาง — "There is a deeper question..." แปลว่ากำลังจะยกประเด็นใหม่ที่ลึกขึ้น
10. The overall structure of the passage:
Correct: B — Claim → supporting reasons → counter-evidence → qualified conclusion.
Why B is correct: Map the paragraphs:
¶1: Introduces the claim.
¶2: Three reasons supporters give.
¶3: Critics' counter-evidence.
¶4: A deeper definitional problem.
¶5: "What can fairly be concluded?" — a qualified, balanced answer.
This is the classic argumentative essay structure — exactly choice B.
Why the other options fail:
- A — no personal story appears anywhere.
- C — there is no list of facts and no call to action.
- D — it isn't a how-to text; no instructions are given.
Strategy tip · Map before answering structure questions
For structure questions, jot one phrase per paragraph in the margin BEFORE looking at the choices. Then match your map against each choice. This prevents being distracted by a single paragraph that "feels like" one of the choices. โจทย์ถามโครงสร้าง — ให้สรุปย่อหน้าละ 1 วลีก่อนดูตัวเลือก เป็นการป้องกันการถูกหลอกด้วยย่อหน้าเดียว
