Carbon Monoxide Poisoning
Carbon monoxide (CO) is a poisonous gas that has is odorless, colorless, and tasteless. These qualities make it possible for you to breathe in toxic amounts of carbon monoxide without realizing that you are in danger.
Carbon monoxide is produced when materials that contain carbon, such as wood, coal, gasoline, oil, or natural gas, are burned. If the space where the materials are burned is not ventilated properly, then the carbon monoxide that is released can build to dangerous levels.
Inhaling carbon monoxide causes the gas to build up in your bloodstream. CO molecules displace oxygen in your blood, depriving your heart, brain, and other organs of oxygen. Early signs of carbon monoxide poisoning include flu-like symptoms, such as dizziness, drowsiness, headache, blurred vision, nausea, and vomiting. Prolonged exposure to large amounts of CO can lead to unconsciousness, irreversible heart, lung, or brain damage, and death.
People who are most at risk of carbon monoxide poisoning include pregnant women, young children, the elderly, and people with serious heart or lung conditions. To prevent carbon monoxide poisoning, people should make sure that places where carbon-containing materials are burned are properly ventilated. Carbon monoxide detectors should also be present in homes, garages, and workspaces.

In paragraph 4, the author includes information about carbon monoxide detectors. The passage does not include information regarding the probability and difficulty in detecting carbon monoxide. Therefore, the idea that it cannot be detected in most cases is not included in the text and is therefore correct for this question.
Inhaling it is not always life-threatening. Incorrect. In paragraph 3, the various effects of carbon monoxide are listed. These symptoms include flu-like symptoms, such as dizziness, drowsiness, headache, blurred vision, nausea, and vomiting. These specific symptoms are not life-threatening, and therefore, it could be stated that inhaling carbon monoxide is not always life-threatening. Since this information is true, it is incorrect for this question.
It can cause a variety of symptoms ranging from mild to severe. Incorrect. In paragraph 3, the variety of symptoms of carbon monoxide poisoning are listed. These symptoms range from mild to severe, including flu-like symptoms, such as dizziness, drowsiness, headache, blurred vision, nausea, and vomiting. Additionally, later in paragraph 3, the symptoms can also include unconsciousness, irreversible heart, lung, or brain damage, and death. Therefore, it can be stated that the symptoms of carbon monoxide poisoning range from mild to severe. Since this information is true, it is incorrect for this question.
It can change the chemicals in your bloodstream. Incorrect. In paragraph 3, the passage states that inhaling carbon monoxide causes the gas to build up in your bloodstream. It goes on to explain how CO molecules displace oxygen in the blood. Therefore, it could be considered accurate that carbon monoxide can change the chemicals in the bloodstream. Since this information is true, it is incorrect for this question.
