Thank you
You're welcome.
The most effective way to prevent carbon monoxide poisoning is by installing and maintaining carbon monoxide detectors. This is option B.
To explain how to arrive at this answer:
1. Read the question carefully: "The most effective way to prevent carbon monoxide poisoning is by..."
2. Consider each option provided:
- Option A: "heating buildings with oil or electricity." This may be a safe heating method, but it doesn't directly address the prevention of carbon monoxide poisoning.
- Option B: "installing and maintaining carbon monoxide detectors." This option directly addresses carbon monoxide poisoning prevention by suggesting the use of detection devices.
- Option C: "keeping an adequate supply of breathing masks at hand." While having masks can be helpful in certain situations, it's not the most effective way to prevent carbon monoxide poisoning.
- Option D: "remaining alert to the odor." While an odor might indicate the presence of carbon monoxide, not all cases of poisoning have a noticeable odor, so relying solely on odor detection is not the most effective approach.
3. Evaluate the options and choose the one that directly addresses carbon monoxide poisoning prevention. In this case, option B, "installing and maintaining carbon monoxide detectors," is the answer.
Therefore, the answer to the question is B. Installing and maintaining carbon monoxide detectors is the most effective way to prevent carbon monoxide poisoning.
