Here are the answers to your questions:
**Question 1:** With which type of galaxy is a small galaxy most likely to merge?
- **Responses:**
- **a much larger galaxy**
- **a nearby galaxy**
(The most common interactions involving small galaxies are with larger galaxies due to gravitational attraction, and a nearby galaxy is likely to be a candidate for merging as well.)
---
**Question 2:** Which factor is essential to the initial formation of galaxies, for either of the theories describing galaxy evolution?
- **Responses:**
- **Small lumps of material merge into larger clumps.**
(This describes a fundamental process in galaxy formation where smaller structures coalesce to form larger galaxies.)
---
**Question 3:** Which characteristics are considered most typical of an old galaxy in decline?
- **Responses:**
- **low gas content, little star formation**
(Old galaxies tend to have depleted gas reserves, which results in reduced star formation activity, indicating their decline.)
