Question

If the tilt of Earth’s axis were increased from
23.5° to 30°, summers in New York State would
become
(1) cooler, and winters would become cooler
(2) cooler, and winters would become warmer
(3) warmer, and winters would become cooler
(4) warmer, and winters would become warmer

Answer 1

Number 1 cooler, and winters would become cooler

Answer 2

If the "tilt" of the Earth's axis were greater than it really is,
then the changes from same-climate-all-year-around, as
well as the changes from same-length-of-daylight-all-year-around,
would increase. 

Summers would become even hotter and Summer daylight
would become even longer. 

Winters would become even colder and Winter daylight
would become even shorter.
