Question

drag and drop the words or phrases that accurately complete the paragraph.
scientists have recognized the enormous sizes of and distances between objects in space. they have come up with units of
that would communicate the relative sizes and relative distances of these
bodies. relative
refers to how big the planets are when compared to each other and the sun.
relative
refers to how far apart the planets are when compared to each other and the sun.
measurement astronomical
galaxy astronomical unit
light year distance universe
size

Explanation:

To solve this, we analyze each blank:

1. First blank: Scientists need units for measuring space objects. "measurement" fits as units of measurement.
2. Second blank: Objects in space (planets, Sun) are "astronomical" bodies (related to astronomy).
3. Third blank: The sentence is about how big planets are (compared to others/Sun), so "size".
4. Fourth blank: The sentence is about how far apart planets are, so "distance".

Filling the blanks:

• First blank: measurement
• Second blank: astronomical
• Third blank: size
• Fourth blank: distance

(Note: The options "astronomical unit" and "light year" are specific units, but the first blank is about the type of unit (measurement), and the last two blanks are about the concepts of size and distance, not specific units. "galaxy" and "universe" don’t fit here as they refer to larger cosmic structures, not the context of relative size/distance of planets.)
