Answer:
(D) The verb should be are because a compound subject joined by and always requires a plural form of the verb.
Explanation:
A compound subject consists of two or more simple subjects that share a verb or verb phrase. These subjects are joined by a conjunction such as and, or, or nor, etc.
Since the two objects mentioned ( i.e window fans and air conditioner) are two different objects that cannot be combined to be one, the sentence is a plural compound sentence and not a singular compound sentence. "Are" is the appropriate conjunction to use.
Explanation:
Several earlier studies have shown the presence of more dust and allergens in carpets compared with non-carpeted floors. At the same time, adverse effects of carpeted floors on perceived indoor air quality as well as worsening of symptoms in individuals with asthma and allergies were reported. Avoiding extensive carpet use in offices, schools, kindergartens and bedrooms has therefore been recommended by several health authorities. More recently, carpet producers have argued that former assessments were obsolete and that modern rugs are unproblematic, even for those with asthma and allergies. To investigate whether the recommendation to be cautious with the use of carpets is still valid, or whether there are new data supporting that carpet flooring do not present a problem for indoor air quality and health, we have reviewed the literature on this matter. We have not found updated peer reviewed evidence that carpeted floor is unproblematic for the indoor environment. On the contrary, also more recent data support that carpets may act as a repository for pollutants which may become resuspended upon activity in the carpeted area. Also, the use of carpets is still linked to perception of reduced indoor air quality as well as adverse health effects as previously reported. To our knowledge, there are no publications that report on deposition of pollutants and adverse health outcomes associated with modern rugs. However, due to the three-dimensional structure of carpets, any carpet will to some extent act like a sink. Thus, continued caution should still be exercised when considering the use of wall-to-wall carpeted floors in schools, kindergartens and offices, as well as in children’s bedrooms unless special needs indicate that carpets are preferable.

There are a lot of reasons why you should spend more time with your family. Below are some reasons why:
1. Even though you, your parents and your siblings don't get along at times, doesn't mean that they hate you or don't love you.
MOST IMPORTANT REASON: Have you ever thought about not wanting to grow up? have you thought about how your parents wont be there with you forever? every second, from the time you are born to the day they die is very valuable. Someday all you have right now is someday going to be gone. you should savor this time as much as possible because when it gets to be to late your parents or siblings pass away, you all of a sudden wish you had spent more time with them. They love you and care for you and even though you may not like them because of consequences they give you or any of that doesn't mean you shouldn't spend time with them and just at least be with them for a little bit. laugh and joke and talk.
One last thing. I don't know if you like Taylor Swift or not but I recommend you go on YouTube and search for 'Never Grow Up' by Taylor Swift. This song will answer your questions way more than I can. I really hope I helped!:)
This persuasive technique is called appeal to authority.
Appeal to authority is a persuasive technique where the speaker relies on the credibility of another person or event to suport their own argument. It is often considered a fallacy because the speaker depends on the "authority"instead of presenting their own evidence.
Example:
"A commercial claims that <u>3 out of 4 dentists</u> would choose this particular brand of toothpaste for their own families to use."
In this statement, the dentists are the authority the argument depends on.
