which of the following is an accurate and specific observation for the graphs below? summer temperatures 1951-1980... summer temperatures 2013-2023... a) people are using their air conditioners more often now than they use to. b) there was significantly more extremely hot days from the years 1951-1980 than 2013-2023. c) the temperatures increased because of climate change. d) there were more days of hot and extremely hot summer temperatures in 2013-2023 and more normal temperature summer days during the years 1951-1980.

Explanation:

• Option a: Talks about air conditioner usage, which is not shown in the temperature graphs. Eliminate.
• Option b: The 2013 - 2023 graph shows more extremely hot days than 1951 - 1980, so this is incorrect. Eliminate.
• Option c: Discusses the cause (climate change), but the question is about observation (what's seen in the graphs), not causation. Eliminate.
• Option d: Accurately describes what's seen: 2013 - 2023 has more hot/extremely hot days, 1951 - 1980 has more normal - temperature days.

Answer:

d. There were more days of hot and extremely hot summer temperatures in 2013 - 2023 and more normal temperature summer days during the years 1951 - 1980.
