Which of the following is an accurate statement about improving air quality?

A. Burning candles can help to mask odors and to clean the air.
B. Humidity should be below 40% to reduce mold and increase children's natural mucus.
C. It's important to ventilate buildings by opening the windows or having a ventilation system.

I was thinking that could be c.

I like c. But go with what you've learned from your text.

it takes me to the c.

thanks Ms.Sue

You're welcome, Priscila.

To determine which option is the most accurate statement about improving air quality, let's examine the options.

Option A suggests that burning candles can help mask odors and clean the air. While candles may help mask odors, they can actually contribute to indoor air pollution, as they release pollutants such as soot and volatile organic compounds (VOCs). Therefore, option A is not the most accurate statement about improving air quality.

Option B states that humidity should be below 40% to reduce mold and increase children's natural mucus. Controlling humidity is indeed crucial for improving air quality. High humidity levels can contribute to mold growth, which can negatively impact air quality and trigger allergies and respiratory problems. However, it is important to note that increasing children's mucus production is not directly related to improving air quality. So, while part of option B is accurate, it may not be the most comprehensive statement about improving air quality.

Option C suggests that it is important to ventilate buildings by opening windows or having a ventilation system. This statement is accurate. Proper ventilation helps remove indoor air pollutants and brings in fresh outdoor air, which can improve air quality. By promoting air circulation, ventilation can reduce the buildup of pollutants and enhance indoor air quality.

Option D states that air quality is often worse outdoors than indoors, so it's important to keep windows closed. While it is true that outdoor air can be more polluted in certain areas or at certain times, keeping windows closed all the time can contribute to poor indoor air quality. Without proper ventilation, indoor air pollutants can accumulate and lead to various health issues. Therefore, option D is not the most accurate statement about improving air quality.

Based on the explanations above, option C is the most accurate statement among the given options. Ventilating buildings by opening windows or using a ventilation system is an effective way to improve air quality.
