Question 1

1.

Downtown Minneapolis records higher temperatures than lakeside and suburban areas. Which TWO factors most directly contribute to this pattern?

Greater area of dark pavement and rooftops that absorb heat

Air near the lakeside traps heat longer at night

Limited tree canopy reduces shade and cooling

The city receives more sunlight than surrounding regions

Wind speeds are higher downtown, dispersing heat rapidly

Question 2

2.

A downtown redevelopment project adds housing but requires rooftop gardens and shaded pedestrian corridors. Which TWO outcomes are most likely based on these design choices?

Storm-water runoff increases due to added soil permeability

Annual CO₂ emissions double because of garden maintenance

Surrounding neighborhoods immediately cool by 10 °F

Average summer surface temperatures in the district decrease slightly

Local air quality improves from additional vegetation

Question 3

3.

Suppose the number of days above 90 °F in Minneapolis rises 20 % by 2045. Which TWO consequences are most consistent with this projection?

Tree growth accelerates automatically as temperatures rise

Urban nighttime temperatures drop because of faster cooling

Electricity demand for cooling increases

Building energy costs decrease due to warmer winters

Heat-related illness risk grows in dense neighborhoods
