Let’s go step by step to solve this worksheet about nonfiction books and the table of contents.

---

First, look at the Table of Contents:

- Stars → page 5
- Planets → page 11
- The Sun → page 19
- The Moon → page 24
- The Milky Way → page 30
- Space travel → page 32

Now answer each question one by one.

---

Question 1: What is a book with the table of contents about?

Look at all the topics listed — they’re all about space! So the book is about space or outer space.

✔ Answer: Space

---

Question 2: Write page numbers for these:

We just read them from the table above.

- moon → 24 (from “The Moon”)
- sun → 19 (from “The Sun”)
- Milky Way → 30

✔ Answers:
moon — 24
sun — 19
Milky Way — 30

Question 3: The index is a list of all the things in the book...

Look at the Index section:

It lists:
- Earth 11, 12, 13
- Mars 15, 16
- Milky Way 30–32
- moon 24–29
- solar 34
- rocket 35, 36

Now answer:

Which pages are about these things?

→ Mars → Look at index: 15, 16

→ moon → Look at index: 24–29

Can you read about Earth on page 25?

Earth is only on pages 11, 12, 13. Page 25 is not in that list.

So → No

Are the index words in alphabetical order?

Check the order:

- Earth
- Mars
- Milky Way
- moon
- solar
- rocket

Wait — let’s check alphabetically:

E comes before M → good
Mars vs Milky Way → both start with M, but “a” comes before “i”, so Mars before Milky Way → good
Milky Way vs moon → “M-i-l-k-y” vs “m-o-o-n” → “i” comes before “o”, so Milky Way before moon → good
moon vs solar → “m” before “s” → good
solar vs rocket → “r” comes before “s” → uh oh!

“rocket” should come BEFORE “solar” if it’s alphabetical.

But here, “solar” is listed before “rocket”. That’s NOT alphabetical.

Wait — actually, looking again:

In the image, the index is written as:

> Earth 11, 12, 13
> Mars 15, 16
> Milky Way 30–32
> moon 24–29
> solar 34
> rocket 35, 36

Alphabetical order would be:

Earth
Mars
Milky Way
moon
rocket
solar

But here, “solar” comes before “rocket” — which is wrong.

So → No, they are NOT in alphabetical order.

Wait — maybe I misread? Let me double-check the actual image layout.

Actually, in many indexes, sometimes entries are grouped differently, but strictly speaking, “rocket” starts with R, “solar” with S — R comes before S.

So if “solar” is listed before “rocket”, then it’s NOT alphabetical.

BUT — wait! In the original problem, the index might be formatted differently. Let me re-read what’s shown.

Looking back at the user’s image description (even though we don’t describe images), the text says:

> Index
> Earth 11, 12, 13 moon 24–29
> Mars 15, 16 solar 34
> Milky Way 30–32 rocket 35, 36

Ah! It’s in two columns!

Left column: Earth, Mars, Milky Way
Right column: moon, solar, rocket

If we read left to right, top to bottom:

Row 1: Earth, moon
Row 2: Mars, solar
Row 3: Milky Way, rocket

That’s not alphabetical either.

But perhaps the intended reading is down the left column first, then down the right?

Left: Earth, Mars, Milky Way → E, M, M → okay
Right: moon, solar, rocket → m, s, r → not sorted.

Alternatively, maybe it’s meant to be read across rows? Still not alphabetical.

Actually — let’s list all index terms in the order they appear:

1. Earth
2. moon
3. Mars
4. solar
5. Milky Way
6. rocket

That’s definitely not alphabetical.

But wait — perhaps there’s a typo in my reasoning? Let’s think like a student.

Maybe the teacher expects us to see that within each column, it’s sorted? Left column: Earth, Mars, Milky Way — E, M, M — not quite (Mars and Milky Way both M, but “a” before “i”, so okay). Right column: moon, solar, rocket — m, s, r — no, rocket should be before solar.

Actually, “rocket” starts with R, which comes before S (“solar”), so if “solar” is listed before “rocket”, it’s out of order.

Therefore, the index words are not in alphabetical order.

But hold on — let’s check the actual standard way indexes work. Usually, they ARE in alphabetical order. Maybe in this case, it IS?

List all terms:

- Earth
- Mars
- Milky Way
- moon
- rocket
- solar

Alphabetical order should be:

Earth
Mars
Milky Way
moon
rocket
solar

In the given index, it’s:

Earth
moon
Mars
solar
Milky Way
rocket

That’s messy. But perhaps the formatting is two columns, and we’re supposed to read vertically?

Column 1: Earth, Mars, Milky Way → E, M, M → acceptable (since Mars < Milky Way)

Column 2: moon, solar, rocket → m, s, r → not sorted (rocket should be before solar)

So overall, no, not fully alphabetical.

However — I recall that in some worksheets, they might consider it alphabetical if major entries are, but here even small ones aren't.

Wait — let's look again at the exact text from the problem:

> Index
> Earth 11, 12, 13 moon 24–29
> Mars 15, 16 solar 34
> Milky Way 30–32 rocket 35, 36

If we ignore the columns and just list all headwords in order of appearance:

1. Earth
2. moon
3. Mars
4. solar
5. Milky Way
6. rocket

Sort them alphabetically:

Earth
Mars
Milky Way
moon
rocket
solar

Compare to given order: Earth, moon, Mars, solar, Milky Way, rocket — completely different.

So clearly not alphabetical.

But — perhaps the question is tricking us? Or maybe I made a mistake.

Another thought: sometimes "moon" is capitalized? No, in the index it's lowercase "moon", while others are capitalized? But in alphabetizing, we usually ignore case.

Still, 'm' for moon, 'r' for rocket, 's' for solar — rocket should come before solar.

Since solar is listed before rocket, it's not alphabetical.

Therefore, answer is no.

But let me confirm with common sense: most indexes ARE alphabetical, so if this one isn't, it's notable.

Perhaps in the context of the worksheet, they expect "yes"? Let's see the other answers.

Wait — looking back at the initial problem statement, it says:

> Are the index words in alphabetical order?

And based on standard rules, no.

But to be thorough, let's list the words as they appear in sequence:

Position 1: Earth
Position 2: moon
Position 3: Mars
Position 4: solar
Position 5: Milky Way
Position 6: rocket

Alphabetical order requires:

After Earth (E), next should be Mars (M), then Milky Way (M), then moon (m), then rocket (r), then solar (s).

Here, after Earth comes moon — which is fine since m comes after e, but then Mars — which also starts with M, but "Mars" vs "moon": M-a-r-s vs m-o-o-n — 'a' comes before 'o', so Mars should come before moon.

In the index, moon is listed before Mars — which is incorrect.

For example, "Mars" should come before "moon" because 'a' < 'o'.

Similarly, "rocket" should come before "solar".

So multiple errors.

Thus, the index is NOT in alphabetical order.

✔ Final decision: no

Now compile all answers:

1. What is the book about? → Space

2. Page numbers:
- moon → 24
- sun → 19
- Milky Way → 30

3. From index:
- Mars → 15, 16
- moon → 24–29
- Can you read about Earth on page 25? → no
- Are index words in alphabetical order? → no
