The Beaufort Wind Scale assigns numbers from 0 to 12 that correlate to a gradient scale of wind velocity and name classification. Meteorologists refer to the wind velocity number 12 on the scale as a hurricane, indicating that the wind velocity is above 65 knots. At the opposite end of the scale, a 0 may include a wind velocity of up to 1 knot, and is called "calm" under the established system.
Which of the following was an assumption made by the creators of the Beaufort Wind Scale?
A. Meteorologists learn the Beaufort Wind Scale in order to classify the level of wind from "calm" to "hurricane."
B. Wind velocity may be measured accurately enough to classify it on a scale from 0 to 12.
C. If a scale assigns names to wind velocity, there must be a corresponding number also assigned.
D. Because it is difficult to measure wind velocity exactly, the Beaufort Wind Scale refers to "calm" as 0, but the wind may be blowing as much as 1 knot.
E. The Beaufort Wind Scale is the most accurate and effective scale for expressing wind velocity.

please explain why E is wrong.
incase i negate E it hurts my conclusion.

Conclusion: The Beaufort Wind Scale assigns numbers from 0 to 12 that correlate to a gradient scale of wind velocity and name classification.
Premise: Meteorologists refer to the wind velocity number 12 on the scale as a hurricane, indicating that the wind velocity is above 65 knots. At the opposite end of the scale, a 0 may include a wind velocity of up to 1 knot, and is called "calm" under the established system.
Assumptions: There are no problems with the plan. Assigning numbers from 0 to 12 is a usable system.
This is an assumption question, as evidenced by the question asking Which of the following was an assumption. Since the question asks for the assumption made by the creators of the Beaufort Wind Scale, the question is asking about the planning pattern.
The standard assumption of a planning reasoning pattern is that there is no problem with the plan. To identify the specific assumption, identify the goal and the plan to achieve the goal. The goal is to create a scale that will correlate to a gradient scale of wind velocity, and the plan is to assign numbers from 0 to 12. The assumption is that the numbers from 0 to 12 will correlate properly to the gradient scale of wind velocity. Evaluate the answer choices, looking for one that matches this assumption. For tougher choices on an assumption question, use the negation test.
Choice A: No. Why the Meteorologists learn the Beaufort Wind Scale is out of scope. This choice does not address the assumption about the creators assigning numbers from 0 to 12 that correlate to a gradient scale of wind velocity.
Choice B: Correct. Wind velocity may be measured accurately enough to classify it on a scale from 0 to 12 directly addresses the assumption. Use the negation test to verify. If the wind velocity could NOT be measured accurately enough to classify it on a scale from 0 to 12, then the Beaufort Wind Scale would not be a useable scale.
Choice C: No. The phrase there must be a corresponding number is extreme language. The choice doesn’t address the assumption that the numbers from 0 to 12 will correlate properly to the gradient scale of wind velocity.
Choice D: No. The statement that it is difficult to measure wind velocity exactly is a reversal of the assumption made by the creators of the scale. The creators of the scale assume that it is not difficult to measure, thus making their scale useful.
Choice E: No. The phrase is the most accurate and effective scale is extreme language. The argument does not address other possible scales.
The correct answer is choice B.
Premise: Meteorologists refer to the wind velocity number 12 on the scale as a hurricane, indicating that the wind velocity is above 65 knots. At the opposite end of the scale, a 0 may include a wind velocity of up to 1 knot, and is called "calm" under the established system.
