In the following question, three short paragraphs about climate change, land–sea warming contrast and aerosols are given in jumbled order. Find the correct sequence of these paragraphs so that they form a meaningful passage about how faster land warming affects air pollution.

Introduction / Context:
This paragraph rearrangement question deals with a scientific topic: climate change, land and ocean warming, and atmospheric aerosols. You are given three paragraphs labelled A, B and C, each containing part of a research description. Your task is to arrange them into a coherent mini-article that introduces the study, explains the underlying concept, and describes the method and results.

Given Data / Assumptions:

• Paragraph A introduces a new study from the University of California, Riverside, mentions a publication date, names the journal, and briefly explains that the land–sea warming contrast drives increased aerosols that harm air quality.
• Paragraph C explains a general principle: land warms faster than ocean when greenhouse gases increase, and this enhanced land warming is associated with aridity, reduced clouds and less rain.
• Paragraph B describes how researchers ran climate change simulations under two scenarios: a business-as-usual warming model and another with less land warming, and explains that enhanced land warming increases aridity and aerosol concentrations.
• Options list possible orders such as ACB, BCA, BAC and CAB.

Concept / Approach:
A logical scientific passage usually begins with an introduction to the study (who did it, where it was published, and the main finding), then moves to the underlying physical principle, and finally explains the methodology or scenarios used to reach the conclusion. Paragraph A clearly plays the role of an introduction. Paragraph C describes the robust response of land warming faster than oceans, which is the physical basis. Paragraph B then gives details of the simulation scenarios and connects enhanced land warming to aerosol increases. Therefore, the natural order is A (study overview), C (principle), B (simulation details and implications).

Step-by-Step Solution:
Step 1: Read paragraph A. It names the institution, journal, date and key result. This is typical of an opening paragraph in a science news article.Step 2: Recognise that after stating the main result, a good passage will explain the mechanism behind it. Paragraph C provides the mechanism: land warms faster than ocean and becomes more arid, causing changes in clouds and rainfall.Step 3: Read paragraph B. It begins with "To determine this, the researchers ran simulations of climate change under two scenarios." The phrase "To determine this" refers back to the previously mentioned effect, which is best captured by paragraph C and the core study described in A.Step 4: Combine A then C then B: A introduces the study and problem, C elaborates the physical response of land and ocean, and B describes how the researchers tested the effect using models.Step 5: Compare this order with the options and note that it corresponds to ACB, which is option A.

Verification / Alternative check:
Try starting with C. That paragraph begins with "A robust response to an increase in greenhouse gases is that the land is going to warm faster than the ocean." While this is a valid statement, it lacks context about why it is being discussed and which specific study is involved. If you then move to A, the text suddenly jumps to a new study without smoothly linking back. Starting with B is even less suitable, because "To determine this" appears in the first sentence with no prior clear referent. Only by placing A first, then C, then B does each paragraph refer back appropriately to something already stated.

Why Other Options Are Wrong:
Option BCA begins with B and leaves the reader wondering what "this" refers to. Option BAC places B before A, which destroys the logical reference chain. Option CAB starts with a general principle in C and then jumps to A, but B, which depends on "this", is left at the end in an awkward position. Only ACB ensures that each pronoun and phrase such as "To determine this" has a clear antecedent.

Common Pitfalls:
Candidates sometimes pay attention only to the scientific content rather than to linking phrases like "To determine this" or "The study". These linking expressions are strong clues for sequencing. A good strategy is to identify which paragraph introduces the topic, which one explains mechanisms, and which one describes methods or results, then arrange them in that logical scientific order.

Final Answer:
The coherent and logically connected order of paragraphs is A C B, so option A (ACB) is correct.
