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.

Answer: a. rock and metals; volatiles</h2>
The Terrestrial Planets are those that are closest to the Sun: Mercury, Venus, Earth and Mars. Among its main characteristics is the fact that they have a <u>metallic core</u> and a <u>silicate mantle </u>that surrounds them. In addition, they have rocks, craters, mountains, valleys and volcanoes on its surface.
on the other hand, Jovian Planets (Jupiter, Saturn, Uranus and Neptune) are classified as <u><em>"gas and ice giants"</em></u>, because they are mainly composed of gas and volatile materials. For example, <u>Uranus and Neptune have higher concentrations of methane </u>(hence its bluish color) and some heavier elements such as <u>oxygen, carbon, nitrogen, and sulfur</u>, while, Jupiter and Saturn have a mixture of <u>hydrogen</u> that gives off a red aspect.
Therefore:
<h2>Terrestrial planets are mainly composed of <u>
rock and metals</u> while Jovian planets are made dominantly of <u>
volatiles</u><u>.</u></h2>
Answer: “They tied me up, then plumb amid ships, back to the mast, lashed to the mast, and took themselves again to rowing.”
Explanation: The aforementioned quotation provides the strongest evidence to illustrate the point that Odysseus is an epic hero.
The members of the crew tied him up, by following his order. Furthermore, Odysseus's crew rows continuously, even after he has been tied up.
