Question

The sentences (A-E) when properly sequenced form a coherent paragraph. Choose the most logical order. 

(A) This is now orthodoxy to which I subscribe—up to a point.
(B) It emerged from the mathematics of chance and statistics.
(C) Therefore the risk is measurable and manageable.
(D) The fundamental concept: Prices are not predictable, but the mathematical laws of chance can describe their fluctuations.
(E) This is how what business schools now call modern finance was born.

• A. ADCBE
• B. EBDCA
• C. ABDCE
• D. DCBEA

Hint:

For paragraph ordering, place definitions/concepts before consequences, then origin/history, and end with evaluation or author's view.

Answer 1

The Correct Option is D

Step 1: Core idea first.
(D) introduces the fundamental concept about price unpredictability but probabilistic description. 

Step 2: Source of the idea.
(B) tells where this concept came from—math of chance and statistics.

Step 3: Consequence.
(C) infers that risk is measurable and manageable. 

Step 4: Naming the field.
(E) concludes that this line of thought gave birth to modern finance. 

Step 5: Author's stance.
(A) provides the author's reflective comment that this is now orthodoxy. \[ \Rightarrow \boxed{\text{Order } D \rightarrow B \rightarrow C \rightarrow E \rightarrow A} \]

Answer 2

Track cause-and-effect connectors instead of building the story chronologically: look for "therefore," "it," and "this is how," and pin each to the exact sentence it must follow.

1. Clue 1: (D) states the core idea, that prices are unpredictable but chance can describe their fluctuations, and is the only sentence general enough to open the paragraph.
2. Clue 2: (C) opens with "Therefore," which must directly follow the reasoning in (D) about fluctuations being describable by chance, making the risk measurable as a direct consequence.
3. Clue 3: (B)'s "It emerged from the mathematics of chance and statistics" then supplies the technical grounding behind the idea just applied, before (E) sums it up as the birth of modern finance.
4. Clue 4: (A)'s reflective "This is now orthodoxy to which I subscribe" only works as a closing personal remark, so it must come last.

Chaining these clues gives the sequence D, C, B, E, A.

Hence, the correct answer is DCBEA.
