I appreciate you sharing this, but I notice a significant issue: the **PASSAGE** you've provided is incomplete. It only contains: > The doctors felt that, although they couldn't put an end to the fighting itself, they could at least help to alleviate the This fragment ends mid-sentence and doesn't contain any underlined portions or standalone digit markers that would correspond to questions Q1–Q5. Additionally, the **QUESTIONS** don't appear to relate to this medical passage at all—they're about CO emissions, home safety, and gas stoves, which don't match the passage content. **To proceed, I need:** 1. The **complete, full passage text** (all paragraphs through the end) 2. Confirmation that the passage OCR includes the standalone digit markers (like "1", "2", "3", etc.) placed right after underlined phrases 3. Confirmation that the questions actually correspond to this passage Could you please provide the complete passage and verify the questions match?

PASSAGE VI

Carbon monoxide (CO) is a colorless, odorless gas produced by burning material that contains carbon, such as coal or natural gas. Carbon monoxide is the leading cause of accidental poisoning deaths in America. The Centers for Disease Control estimates that carbon monoxide poisoning claims nearly 500 lives and causes more than 15,000 visits to hospital emergency departments annually. Common household appliances produce carbon monoxide. When not properly ventilated, carbon monoxide emitted by these appliances can build up. The only way to detect carbon monoxide is through testing, using a specialized sensing device.

Gas stoves have been known to emit high levels of carbon monoxide. Average carbon monoxide levels in homes without gas stoves vary from 0.5 to 5.0 parts per million (ppm). Levels near properly adjusted gas stoves are often 5.0 to 15.0 ppm and those near poorly adjusted stoves may be 30.0 ppm or higher. CO levels between 0.5 and 15.0 ppm are considered safe.

Table 1 shows the carbon monoxide levels in ppm for each of five homes, with and without gas stoves.

1. According to the passage, which of the following homes listed in Table 1 most likely has a poorly adjusted gas stove?

2. A sensing device was installed in Home 2 to test CO levels. Which of the following is most likely true about the results of the test?

3. According to the passage, which of the following carbon monoxide levels would be considered most harmful?

4. According to the passage, if Home 4 has a gas stove, should it be removed?

5. Suppose a 6th home was tested for carbon monoxide and the results showed a carbon monoxide level of 10.0 ppm. According to the passage, which of the following conclusions can be reached?
