3. Worked Example
Scenario:
During an exam you are given a description and asked to identify the country:
“This country shares its borders with six nations, has a population of about 135 million, its capital is Ankara, and it is known for the ancient city of Troy.”
Solution Steps
-
Identify the key clues
- Borders six countries → candidate list: Turkey, Ethiopia, etc.
- Capital Ankara → strongly points to Turkey.
- Population ~135 M → matches Turkey’s 2024 estimate (~84 M; but the clue may refer to older data).
- Ancient city of Troy → famous in Turkey.
-
Cross‑check
- Turkey borders: Greece, Bulgaria, Georgia, Armenia, Iran, Iraq, Syria. (Exactly 6 countries)
- Population indeed ~85 M (2024), but the exam might use older data.
-
Answer
- Turkey
Takeaway:
- Use unique identifiers (capital city, famous landmark, number of borders) to pinpoint the country quickly.
