SAT考試會在閱讀題目當中設計一定的邏輯題來考察考生的基本的思維能力，據邏輯題考察統計（統計口徑：OG8＋真題下冊8套），邏輯題中的類比題型是14個，占有較大的比重，下面我們通過實例來進行分析。

　　邏輯題――類比

　　真題上冊-OC題：

　　Black holes are the most efficient engines of destruction known to humanity. Their intense gravity is a one-way ticket to oblivion, and material spiraling into them can heat up to millions of degrees and glow brightly. Yet, they are not all-powerful. Even super massive black holes are minuscule by cosmic standards. They typically account for less that one percent of their galaxys mass. Accordingly, astronomers long assumed that super massive holes, let alone their smaller cousins, would have little effect beyond their immediate neighborhoods. So it has come as a surprise over the past decade that black hole activity is closely intertwined with star formation occurring farther out in the galaxy.

　　Q: Which of the following most resembles the relationship between black hole activity and star formation as described in the passage?

　　 A volcanic eruption on one continent results in higher rainfall totals on another continent.

　　 Industrial emissions in one region lead to an increase an airborne pollutants in adjacent regions.

　　 A drought in a wilderness area causes a significant loss of vegetation in that area

　　 Decreased oil production in one country results in higher gas prices in oil-dependent countries.

　　 Overfishing in a gulf leads to an increase in the population of smaller aquatic organisms.

　　這道題的關鍵是找到題目中類比的點，當讀者理解了題目所表現的關系時，就可以抽象出這個題目類比的點了，即理論上不可能發生的實際卻發生了，然后通讀選項，只有A符合這個類比的點，其他的選項都是理論上可以發生，實際也發生這么一點。
