Nhận diện Inference Questions

Các từ khóa thường gặp trong đề:

Từ khóa Ví dụ
imply / implication What does the author imply about…?
suggest The passage suggests that…
infer It can be inferred from the passage that…
likely The author would most likely agree that…
conclude What can be concluded from paragraph B?

Phân biệt: Inference vs. Stated Information

Loại Đặc điểm Ví dụ
Stated (nói thẳng) Có thể tìm nguyên văn trong bài “The population grew by 20%”
Inference (suy luận) Phải kết hợp thông tin để rút ra kết luận Bài nói dân số tăng + thiếu nhà ở → suy ra: nhu cầu nhà ở tăng
Over-inference (suy quá) Đi xa hơn những gì bài viết hỗ trợ Suy ra: chính phủ thất bại → KHÔNG có cơ sở

📝 Chiến lược trả lời Inference Questions

Bước 1: Xác định phạm vi

Câu hỏi hỏi về đoạn nào? Tập trung vào đoạn đó + đoạn liền kề.

Bước 2: Tìm evidence (bằng chứng)

Mọi inference đúng đều phải có bằng chứng trong bài. Nếu không tìm được evidence → đáp án sai.

Bước 3: Loại trừ

Loại đáp án sai Cách nhận diện
Quá cực đoan Dùng always, never, completely, all
Quá xa Đi quá xa so với thông tin trong bài
Ngược nghĩa Nói ngược lại ý bài viết
Không liên quan Đúng nhưng bài không đề cập

Passage: The Hidden Costs of Tourism

(Thời gian: 20 phút — Bấm giờ!)

A. Tourism is often celebrated as a powerful engine of economic growth. Governments around the world invest heavily in promoting their countries as travel destinations, highlighting the jobs created in hotels, restaurants, transport, and entertainment. According to the World Travel and Tourism Council, the tourism industry contributed approximately 10.4% of global GDP in 2019 and supported over 330 million jobs worldwide. For many developing nations, tourism represents one of the primary sources of foreign currency and has been credited with lifting communities out of poverty.

B. However, the economic benefits of tourism are not always distributed as evenly as official statistics might suggest. In many popular destinations, a significant proportion of tourism revenue flows to large international hotel chains and tour operators rather than to local businesses. A study by the United Nations Environment Programme estimated that in some developing countries, as much as 80% of tourism expenditure “leaks” back to the tourists’ home countries through foreign-owned companies, imported goods, and overseas marketing costs. Local workers, while gaining employment, often receive low wages and face seasonal job insecurity, with many positions offering little opportunity for career advancement.

C. The environmental impact of mass tourism has become increasingly difficult to ignore. Popular natural attractions, from coral reefs in Southeast Asia to national parks in East Africa, face mounting pressure from visitor numbers that far exceed their carrying capacity. In Thailand, the famous Maya Bay — made globally recognisable by the film “The Beach” — was closed to tourists indefinitely in 2018 after scientists found that the coral reef had been severely damaged by the 5,000 daily visitors. Similarly, Venice has introduced visitor caps and entry fees in an attempt to manage the estimated 30 million tourists who visit the city annually, outnumbering its resident population of fewer than 50,000 by a ratio of more than 600 to 1.

D. Cultural erosion represents another frequently overlooked consequence of tourism. As destinations reshape themselves to meet tourist expectations, authentic local traditions can become commodified and simplified into easily consumable performances. In Bali, for example, sacred temple ceremonies that once held deep spiritual significance are now sometimes performed multiple times daily for tourist audiences, stripped of their original religious context. Sociologists have described this process as “staged authenticity” — the creation of experiences that appear genuine but are fundamentally altered to suit outsiders’ preferences.

E. Some destinations have begun exploring alternative models that attempt to balance economic benefits with environmental and cultural preservation. Bhutan’s approach is perhaps the most distinctive: the country limits tourist numbers through a mandatory daily fee of $200 per visitor, using the revenue to fund conservation and community development. Costa Rica has positioned itself as a leader in ecotourism, with over 25% of its land area designated as protected reserves. New Zealand’s tourism board has shifted its marketing strategy from attracting maximum visitor numbers to encouraging “high-value, low-impact” tourism that generates revenue while minimising environmental damage.

F. Despite these innovative approaches, critics argue that sustainable tourism remains a niche concept that has yet to challenge the dominant model of mass tourism. The fundamental tension between tourism as an industry driven by growth and tourism as a force for preservation has not been resolved. As global travel continues to recover following the pandemic, the choices made by governments, businesses, and individual travellers in the coming years will determine whether tourism can truly become a force for good or whether its hidden costs will continue to mount.

✅ Đáp án & Giải thích

Câu 1-6: Inference Questions

Câu Đáp án Giải thích
1 B Đoạn B nói 80% revenue “leaks” ra nước ngoài → lợi ích thực tế cho địa phương thấp hơn thống kê
2 C Maya Bay bị đóng cửa do coral reef bị hủy hoại → ví dụ cho environmental damage
3 C “Stripped of their original religious context” — tác giả dùng từ tiêu cực → lo ngại
4 C “Using the revenue to fund conservation and community development” — dùng phí để làm điều tốt
5 B “Remains a niche concept that has yet to challenge the dominant model” → khó trở thành mainstream
6 C “Not always distributed as evenly as official statistics might suggest” → thống kê quá lạc quan

Câu 7-10: Y/N/NG

Câu Đáp án Giải thích
7 NO Đoạn A thừa nhận tourism đóng góp GDP, tạo việc làm
8 YES “30 million tourists… resident population of fewer than 50,000”
9 NOT GIVEN Bài nói $200/ngày nhưng không so sánh với nước khác
10 YES “Over 25% of its land area designated as protected reserves”

💡 Inference Questions: Những lỗi thường gặp

Lỗi Ví dụ Cách tránh
Over-inference Bài nói du lịch có hại → suy ra “nên cấm du lịch” Chỉ suy luận trong phạm vi bài viết
Dùng kiến thức bên ngoài Bạn biết thêm về Maya Bay → chọn đáp án dựa trên đó Chỉ dùng thông tin TRONG bài
Chọn đáp án quá mạnh “Always”, “never”, “completely” Ưu tiên đáp án vừa phải: “may”, “some”, “often”
Nhầm stated với inferred Chọn thông tin nói thẳng trong bài Inference = kết hợp thông tin → rút ra kết luận
