B. Thermometer
Explanation
Galileo's invention of the thermometer is the correct answer because it is well-known that he developed an early version of the instrument in the late 16th century. This invention is particularly significant in relation to the question's context of needing money to support his family because Galileo's thermometer gained popularity and was sold to generate income. Additionally, the thermometer was a practical invention that had various applications, making it a logical choice for someone seeking financial stability.

### Galileo Galilei was determined to attempt to construct his own ___________.

Syglass
Explanation
After a frantic 24 hours of experimentation, working only on instinct and bits of rumors, never having actually *seen* the Dutch spyglass, he built a 3-power telescope. After some refinement, he brought a 10-power telescope to Venice and demonstrated it to a highly impressed Senate. His salary was promptly raised, and he was honored with proclamations.

### What was Galileo's observation on the Moon?

• A.

It was smooth

• B.

Uneven, rough, and full of cavities and prominences.

• C.

cracked

• D.

All of the above

• E.

None of the above

B. Uneven, rough, and full of cavities and prominences.
Explanation
Galileo's observation on the Moon was that it was uneven, rough, and full of cavities and prominences. This means that he observed that the Moon's surface was not smooth, but rather had various irregularities and features such as craters and mountains.

Explanation
On January 7, 1610, he turned his 30 power telescope towards Jupiter, and found three small, bright stars near the planet. One was off to the west, the other two were to the east, all three in a straight line. The following evening, Galileo once again took a look at Jupiter, and found that all three of the "stars" were now west of the planet, still in a straight line!
Observations over the following weeks lead Galileo to the inescapable conclusion that these small "stars" were actually small satellites that were rotating about Jupiter. If there were satellites that didn't move around the Earth, wasn't it possible that the Earth was not the center of the universe?
