Which of the following are characteristics of most large cities? They I. have large populations II. are…

Analyze the question: We need the characteristics common to most large cities. The key word is "most," so we look for features that apply almost universally.

Explain the concept: A city is a large, permanent settlement with a high population and a range of functions. Cities typically perform several functions:

• Commercial/trade: markets, banks, shops and industries. Large cities grow because of trade and economic activity.
• Administrative: many cities serve as local, state or national government headquarters.
• Religious: only some cities (e.g. Mecca, Jerusalem, Rome/Vatican) are primarily religious centers.

Step-by-step evaluation:

• I. Large populations ✔ This is the defining feature of a large city.
• II. Administrative centers ✔ in many cases. Most large cities are capitals of states, regions or countries (Lagos, Kano, Ibadan, Abuja), but not all. Some big cities are purely commercial or industrial and are not capitals (e.g. Lagos is no longer Nigeria's capital, though it is a state capital).
• III. Religious centers ✘ Only a few cities are known mainly for religion. This is not typical of most large cities.
• IV. Commercial centers ✔ Almost every large city has major commercial activity, since trade and industry are what attract and sustain large populations.

Which pair is best? Populations (I) and commercial function (IV) are true of virtually all large cities. Administrative function (II) is common but not universal, and religious function (III) is not typical. So among the options, I and IV only is the most defensible answer. Option D (II and IV) leaves out the large population, which is the most basic feature of a large city.

Answer: B. I and IV only

Exam tip: When you see "most" or "characteristics of," go for features that are universal (population size, commerce) and avoid specialized functions like religion that only apply to particular cities.
