Let's analyze the given jumbled sentences to arrange them in a logical order to form a coherent paragraph. The sentences describe the process of answering multiple-choice questions and marking them on an answer sheet.

The sentences are:

1. On the answer sheet, darken the circle of the correct answer against each question.
2. You must select the best answer for each question.
3. Every question is followed by four answer choices marked 1, 2, 3 and 4.
4. If you darken more than one circle, the answer will be counted as wrong.

To arrange these sentences, let's think about the natural flow of actions when answering a multiple-choice question:

• First, you need to know the format of the question.
• Then, you decide which answer is correct.
• After deciding, you mark your answer on the answer sheet.
• Finally, there might be specific rules about how to mark to avoid errors.

Let's map the sentences to this flow:

• Sentence C describes the format of the question (four choices). This is a good starting point as it sets the context.
• Sentence B tells you what you need to do (select the best answer). This logically follows knowing the choices are available.
• Sentence A explains how to record your selection (darken the circle on the answer sheet). This comes after you have selected the answer.
• Sentence D provides a cautionary rule about marking (what happens if you darken more than one circle). This rule is related to the action described in Sentence A and serves as an important instruction after the marking process is mentioned.

Following this logical progression, the correct order is C, followed by B, then A, and finally D.

Let's read the paragraph in the order CBAD:

Every question is followed by four answer choices marked 1, 2, 3 and 4. You must select the best answer for each question. On the answer sheet, darken the circle of the correct answer against each question. If you darken more than one circle, the answer will be counted as wrong.

This arrangement forms a clear and meaningful paragraph explaining how to handle multiple-choice questions on an answer sheet.

Therefore, the correct sequence is CBAD.

Additional Information: Paragraph Arrangement Tips

Arranging jumbled sentences to form a coherent paragraph is a common type of verbal ability question. Here are some tips:

• Identify the topic sentence: Look for a sentence that introduces the main subject or idea. This is often the first sentence.
• Look for connecting words: Words or phrases like "therefore," "however," "in addition," "for example," "this," "these," pronouns (he, she, it, they), or time indicators (first, then, finally) can help link sentences.
• Establish the flow: Determine the chronological order, cause and effect, general to specific, or problem and solution sequence.
• Check pronoun references: Ensure pronouns refer back to previously mentioned nouns correctly.
• Read the arranged paragraph: After arranging, read the full paragraph to see if it makes logical sense and flows smoothly.
