Question

which of the following is true of slippery roads?
shaded areas may have hidden ice spots that freeze first/dry last
bridges and overpasses usually freeze before roads do
wet leaves cause slipping, and wet ice is slicker than ice alone
all of the above

Explanation:

• Shaded areas can have ice that freezes first/dries last.
• Bridges/overpasses freeze before roads (due to air on both sides cooling them faster).
• Wet leaves reduce friction (cause slipping), and wet ice is slicker than dry ice. So all statements are true.

Answer:

D. All of the above
