Answer:
<em></em>
- <em>There are 30 experimental units in the experiment, which are the 30: the thirty sheets of metal.</em>
Explanation:
This table shows you how the <em>experimental</em> units, <em>sheets of metal</em>, were treated:
Metal 1 Metal 2 Metal 3 Total
Paint A 5 5 5 15
Paint B 5 5 5 15
Total 10 10 10 30
Fifteen sheets (units) were treated with <em>paint A</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.
Fifteen sheets (units) were treated with <em>paint B</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.
Answer:
E. strengthen a claim by indicating that it applies even to exceptional cases
Explanation:
Answer E
Correct. In this sentence, the author makes the claim that melancholy can make one’s imagination “torpid” (sluggish), and that lack of appropriate occasions can prevent the mind from coming up with “sallies and excursions” (clever remarks). He strengthens the claim by extending it to the most exceptional cases when he indicates that it applies to any mind “however volatile,” that is, even to those that are normally the liveliest and most wide-ranging.

❄<u>Edwin Hubble made many important contributions to astronomy. Up until his observations in 1922, scientists were of the opinion that the universe consisted of only one galaxy: the Milky Way. Hubble's observations of Cepheids and subsequent measurement of their distances (using Henrietta Swan Leavitt's calculations) showed that many celestial objects were too far away to be part of the Milky Way and were actually galaxies themselves.❄</u>
<u>❄By calculating the distances to many newly found galaxies, Hubble also discovered that the galaxies were receding away from Earth and that the speed of recession was proportional to the distance. This established the fact that the universe was expanding, which changed the entire consensus (from the time of Newton) that the universe was finite. It also backed up Georges Lemaître's theory that the universe had a beginning (later called the Big Bang).❄</u>
