Which of these must have happened first? A.Research determined that a 1,000-acre (405-hectare) forest would remove 4 to 7 short tons (3.6 to 6.4 metric tons) of nitrogen oxide annually. B.The EPA required companies to rid the air of industrial pollutants, such as nitrogen oxide, emitted by factories. C.After reading a notation that suggested that reforestation could improve air quality, Dow Chemical and the Nature Conservancy decided to research how the idea might work. D.Another scientific group researched a similar idea to the one Dow Chemical and the Nature Conservancy proposed and decided that it would not pay off.
Based on the information provided, the correct chronological order would be:
1. D. Another scientific group researched a similar idea to the one Dow Chemical and the Nature Conservancy proposed and decided that it would not pay off.
2. C. After reading a notation that suggested that reforestation could improve air quality, Dow Chemical and the Nature Conservancy decided to research how the idea might work.
3. B. The EPA required companies to rid the air of industrial pollutants, such as nitrogen oxide, emitted by factories.
4. A. Research determined that a 1,000-acre (405-hectare) forest would remove 4 to 7 short tons (3.6 to 6.4 metric tons) of nitrogen oxide annually.
what is the answer?
The correct chronological order is:
1. Another scientific group researched a similar idea to the one Dow Chemical and the Nature Conservancy proposed and decided that it would not pay off.
2. After reading a notation that suggested that reforestation could improve air quality, Dow Chemical and the Nature Conservancy decided to research how the idea might work.
3. The EPA required companies to rid the air of industrial pollutants, such as nitrogen oxide, emitted by factories.
4. Research determined that a 1,000-acre (405-hectare) forest would remove 4 to 7 short tons (3.6 to 6.4 metric tons) of nitrogen oxide annually.
Therefore, the correct answer is D. Another scientific group researched a similar idea to the one Dow Chemical and the Nature Conservancy proposed and decided that it would not pay off.
To determine the correct chronological order of these events, we need to analyze the given information and determine which events are dependent on or related to other events. Here's a breakdown of each event:
A. Research determined that a 1,000-acre forest would remove nitrogen oxide annually.
B. The EPA required companies to rid the air of industrial pollutants, such as nitrogen oxide.
C. Dow Chemical and the Nature Conservancy decided to research reforestation's potential impact on air quality after reading a related notation.
D. Another scientific group researched a similar idea and concluded that it would not be beneficial.
Now, let's examine the dependencies between these events:
- Event A (research on the nitrogen oxide removal capacity of a forest) doesn't explicitly depend on any other event mentioned.
- Event B (EPA requirement to reduce industrial pollutants) seems independent and unrelated to other events.
- Event C (Dow Chemical and the Nature Conservancy deciding to research reforestation's impact) is influenced by reading a notation, but no direct dependency on other events is stated.
- Event D (another scientific group concluding a similar idea wouldn't pay off) appears independent and unrelated to other events.
Based on this analysis, we can determine the chronological order as follows:
1. Event A: Research determining the forest's nitrogen oxide removal capacity.
2. Event B: The EPA requirement for companies to reduce nitrogen oxide emissions.
3. Event C: Dow Chemical and the Nature Conservancy deciding to research reforestation's impact.
4. Event D: The other scientific group concluding that the similar reforestation idea wouldn't be beneficial.
Therefore, the correct order is A, B, C, D.
