(06.04 MC) An ecologist suspects that an otherwise healthy forest ecosystem experienced an unusually high level of acid deposition during a snowy winter. Here are the observations made: There are high numbers of trees with leaves that are damaged. There is an unusually high level of aluminum in the soil. The pH of the snowmelt is below 5. Which of the observations could have led the ecologist to suspect the high acid deposition?

(06.05 MC) Read the following excerpt from the U.S. National Library of Medicine related to noise pollution, then answer the question that follows: In our study, we found that 20% of respondents complained of health problems and many identified symptoms that could be related to exposure to loud sounds, such as anxiety, stress, nervousness, irritability, and fatigue. Some even mentioned hearing symptoms such as tinnitus, hearing loss, and difficulty understanding speech, but none associated the symptoms to exposure. Nevertheless, the number of respondents who are unaware of the effects of noise (70%) and do not protect themselves from it (72%) was elevated, even among those who work in industry (33%) and formally receive guidance on the subject. In any case, if we do not create expectations of a certain event, it will hardly be valued as important. Floriani affirms that ecological problems only become a matter of concern when they impose significant harm to human beings and nature. Most participants state that noise does not bother them, does not interfere with performance of tasks, and do not recognize themselves as producers of noise. The population exposed to urban noise, even though aware of its presence, has no awareness of the effects that it can cause, which hinders initiatives being taken aimed at minimizing these effects. It is also necessary to think that it is common the sense of resignation and impotence before issues and situations involving modernity, among them noise pollution. After all, noise is an inherent part of the evolution of societies after the advent of the industrial revolution. Which of the following statements supports the need for understanding the impacts of noise pollution?
