I appreciate your submission, but I need to clarify an important issue: The content you've provided appears to be **two graphs/charts and a set of multiple-choice questions**, not an ACT English passage with underlined text to format. The instructions I follow are designed to: 1. Take an OCR'd English **passage** (prose text with underlined portions and embedded question markers) 2. Render it as HTML with `` and `` tags What you've provided instead seems to be: - A data visualization (coordinate axes, amplitude/tension legend, time scale) - Science/physics questions about wave behavior, tension, amplitude, and wave speed - No underlined English phrases to mark up **To help you, I need:** - An actual **English passage** (readable prose text) - The passages should contain underlined phrases marked with standalone digits - Those questions should ask about grammar, word choice, punctuation, etc. If you have an ACT English section passage, please provide: 1. The OCR'd passage text (with digit markers where underlines are) 2. The multiple-choice questions labeled Q1, Q2, etc. Then I can format it correctly as HTML.

A group of students gathered data to determine the factors that affect the speed of a wave pulse as it travels down a spring. They studied springs with their coils stretched out (high tension) against springs with looser coils (low tension) to determine how changing the characteristics of the medium affect wave speed. They also studied the effect of wave amplitude on the speed of the wave. Amplitude is the size of the disturbance.

The students conducted slow-motion video analysis of a wave pulse traveling down the spring and graphed the total distance the pulse traveled versus the total travel time, as shown in Figure 7.3.

1. To properly determine the effect of wave amplitude on wave speed, the students must:

2. According to Figure 7.3, the average speed of the high-tension/high-amplitude wave is closest in value to:

3. According to Figure 7.3, the low-tension/low-amplitude wave:

4. According to Figure 7.3, what is the effect of the tension of the spring on wave speed?

5. What is the effect of amplitude on wave speed?

6. Because sound behaves like a wave, one can infer from the results in Figure 7.3 that loud sounds:

7. It is believed that light has the same characteristics as waves. From the results in Figure 7.3, one can infer that:

8. Water waves behave like spring waves in many ways. From the results in Figure 7.3, one can conclude that a water wave:

9. Assuming the low-tension/low-amplitude wave was able to keep moving, what is the approximate distance it would travel in 6.0 seconds?

10. In another experiment with springs, a large wave travels 10.2 m along a spring in 5.3 seconds. Approximately how much time would it take a small ripple to travel the same distance?
