I appreciate you providing the questions, but I notice the PASSAGE text you've shared is incomplete. You've given me only: ``` becoming to decide ``` This appears to be a fragment that doesn't form coherent sentences, and it's unclear where the question-markers (standalone digits) should be placed or which phrases should be underlined. To produce accurate HTML output, I need: 1. **The complete, full passage text** — ideally the entire paragraph(s) as they appear in the original ACT material, including any standalone digits that mark question locations. 2. **Confirmation of the question range** — you've listed Q1–Q5, so I assume there are 5 underlined portions or question-insertion points. Could you please provide the complete passage text? Once I have that, I'll render it as HTML with proper `...N` formatting.

PASSAGE III

Predation is an interaction between individuals of 2 species in which one is harmed (the prey), and the other is helped (the predator). Predation can occur among plants and animals as well as between plants and animals. Some biologists contend that herbivores, or plant eaters, are predators. Table 1 indicates some characteristics and examples of certain predators.

Predation is very important in maintaining a natural balance in any given ecosystem. For example, without predators, prey populations tend to grow exponentially. Without prey, predator populations tend to decline exponentially. Predators consume individual members of the prey population, thereby controlling the overall numbers in the ecosystem. The number of prey consumed depends on the number of prey present as well as the number of predators present. The rate of change in the number of prey is a function of the birth of new prey minus the death of other prey, due either to predation or other causes. The death rate is assumed to depend on the number of prey available and the number of predators. The rate of change in the number of predators is a function of the births of new predators-which depends on the number of prey-minus the death of some predators.

Over long periods of time, predator and prey tend to balance each other out. This is called the predator-prey cycle. Prey numbers will increase when predator numbers decrease. When the number of prey reaches a certain point, predators will start to increase until they eat enough prey to cause a decline in prey numbers. When this happens, the number of predators will begin to decrease because they can't find enough prey to eat, and the cycle will begin again. Figure 1 represents an example of a predator-prey cycle.

Figure 1

1. Based on information in the passage and in Table 1, an herbivore is:

2. According to information in the passage, the number of prey consumed in an ecosystem is dependent on:

3. Based on Figure 1, during the first year, predator numbers:

4. Studies have shown that a certain species of deer will only eat a specific type of plant found in the deer's natural habitat, and nothing else. Is this finding supported by the information in the passage?

5. Based on Figure 1, during which year were the greatest number of prey animals available?
