Irregulars typically have very few blue stars.

Indicate whether the statement is true or false

Question 2

Consider the following statement, and explain whether or not it is sensible: Last night I saw Mars move westward through the sky in its apparent retrograde motion.

What will be an ideal response?

Answer to Question 1

FALSE

Answer to Question 2

This statement does not make sense because the apparent retrograde motion is noticeable only over many nights, not during a single night. (Of course, like all celestial objects, Mars moves from east to west over the course of every night.)
