Review: Galaxies I
Explanation
In this question, we are asked about M32, the dwarf
elliptical. Why isn't it spiral? The attributes are introduced in the first
paragraph, while they are explained (and explain other things) in the second
paragraph, so we go to the second paragraph. Line 19 to 21 has it: "M32 may
have had a spiral shape earlier that was transformed by a tidal field from
Andromeda into its current elliptical shape." That corresponds directly to
answer choice (E).
The correct answer is (E).
