Question

Read the sentences and choose the option that best arranges them in a logical order.
A. To help control this runoff and to generate hydroelectric power, the Lower Colorado River Authority operates a series of dams that form the Texas Highland Lakes.
B. The eastern part of the city is relatively flat, whereas the western part and western suburbs consist of scenic rolling hills on the edge of the Texas Hill Country.
C. The city is also situated on the Balcones Fault, which, in much of Austin, runs roughly the same route as Loop 1 (Mopac Expressway).
D. The lakes also provide venues for boating, swimming, and other forms of recreation within several parks located on the lake shores.
E. Because the hills to the west are primarily limestone rock with a thin covering of topsoil, portions of the city are frequently subjected to flash floods from the runoff caused by thunderstorms.

• A. CBADE

Hint:

In sequencing questions, always start with broad geographical or contextual information before moving to causes, effects, and finally additional details.

Answer 1

The Correct Option is D

Step 1: Identify the introductory sentence.
Sentence C introduces the city's geological position on the Balcones Fault, making it the correct starting point.
Step 2: Follow with geographical description.
Sentence B expands on Austin’s physical geography—east flat, west hilly—logically following C.
Step 3: Explain the consequence.
Sentence E explains the impact of the western hills' composition, connecting runoff and flash floods to the geography in B.
Step 4: Describe the solution to the problem.
Sentence A then fits naturally, explaining how the Lower Colorado River Authority uses dams to control runoff.
Step 5: Conclude with recreational details.
Sentence D finally adds extra information about how the lakes are also used for recreation.
Step 3: Conclusion.
Thus the correct logical sequence is C → B → E → A → D.
