A.I. Explanation:

Option 1: "The city streets were able to witness the increasing temperature slowly."

Explanation: This option suggests a gradual increase in temperature, which contradicts the text's description of 'blistering temperatures' and the immediate impact of the urban heat island effect. The text emphasizes the rapid heating of urban areas, not a slow process.

Option 2: "The temperature of the urban areas has been increasing as compared to the local areas."

Explanation: While this option touches on the comparison between urban and rural areas, it lacks specificity regarding the cause of the temperature increase. The text focuses on the urban heat island effect and its consequences, rather than simply stating that urban temperatures are higher.

Option 3: "The energy demands and air pollution increases in the rural areas."

Explanation: This option incorrectly shifts the focus to rural areas, whereas the text discusses the urban heat island effect and its impact on urban environments. The text does not mention energy demands or air pollution in rural areas, making this option irrelevant.

Option 4: "The blacktop is somehow responsible for the increased temperature in the urban areas."

Explanation: This option accurately reflects the main idea of the text, which highlights how urban materials like blacktop contribute to higher temperatures. The quote from Lauren Nash supports this by explaining how concrete and blacktop warm up faster, leading to the urban heat island effect.
