Moons of Dwarf Planets
| Dwarf planet name | Number of moons | Name of moons |
|---|---|---|
| Haumea | 2 | Hi'iaka, Namaka |
| Ceres | 0 | N/A |
| Makemake | 1 | MK 2 |
| Eris | 1 | Dysnomia |
| Pluto | 5 | Charon, Nix, Kerberos, Styx, Hydra |
Like Earth, some dwarf planets in the solar system have exactly one moon. Two examples of such dwarf planets are ______
Which choice most effectively uses data from the table to complete the statement?
A
Eris and Makemake.
B
Haumea and Eris.
C
Pluto and Haumea.
D
Makemake and Ceres.
Solution
Step 1: Decode and Map the Passage
Part A: Create Passage Analysis Table
| Text from Passage | Analysis |
|---|---|
| "Moons of Dwarf Planets" [Table Title] |
|
| Table with columns: Dwarf planet name, Number of moons, Name of moons |
|
| "Haumea | 2 | Hi'iaka, Namaka" |
|
| "Ceres | 0 | N/A" |
|
| "Makemake | 1 | MK 2" |
|
| "Eris | 1 | Dysnomia" |
|
| "Pluto | 5 | Charon, Nix, Kerberos, Styx, Hydra" |
|
Part B: Passage Architecture & Core Elements
Main Point: The table provides data about how many moons each dwarf planet has, with the question asking us to identify which ones have exactly one moon like Earth.
Step 2: Interpret the Question Precisely
This is a fill-in-the-blank question asking us to choose the best logical connector. The answer must create the right relationship between what comes before and after the blank.
Step 3: Prethink the Answer
- Looking at our table analysis, we need to find dwarf planets with exactly 1 moon
- Haumea has 2 moons - too many
- Ceres has 0 moons - too few
- Makemake has 1 moon - perfect match
- Eris has 1 moon - perfect match
- Pluto has 5 moons - way too many
- So the right answer should pair Makemake and Eris, since they're the only two dwarf planets in the table that have exactly one moon each
Answer Choices Explained
A
Eris and Makemake.
✓ Correct
- Identifies Eris (1 moon) and Makemake (1 moon)
- Both dwarf planets have exactly one moon, matching Earth's situation
- Directly supported by the data table
B
Haumea and Eris.
✗ Incorrect
- Pairs Haumea and Eris
- While Eris has 1 moon (correct), Haumea has 2 moons
- This trap targets students who focus on just one correct planet (Eris) and miss that Haumea doesn't fit the criteria
C
Pluto and Haumea.
✗ Incorrect
- Pairs Pluto and Haumea
- Pluto has 5 moons and Haumea has 2 moons
- Neither planet has exactly one moon like Earth
D
Makemake and Ceres.
✗ Incorrect
- Pairs Makemake and Ceres
- While Makemake has 1 moon (correct), Ceres has 0 moons
- This trap targets students who might confuse "exactly one moon" with "few moons" and think 0 is close enough to 1
