Problem Description:

The task is to match each prefix in the left column with the corresponding word that uses the same prefix in the right column. A prefix is a group of letters added to the beginning of a word to modify its meaning.

Solution:

#### Step 1: Understand the prefixes and their meanings
- ex-: Out of, away from (e.g., expand)
- inter-: Between, among (e.g., interstate highway)
- anti-: Against, opposed to (e.g., antigravity backpack)
- pre-: Before (e.g., pre-game)
- counter-: Opposite, against (e.g., counterattack)
- en-: Make, cause to be (e.g., enlighten)
- extra-: Beyond, more than (e.g., extraordinary)
- trans-: Across, through (e.g., transcontinental)
- under-: Below, beneath (e.g., underestimate)
- semi-: Half, partly (e.g., semi-truck)
- over-: Above, too much (e.g., overcompensate)
- extra-: Beyond, more than (e.g., extraordinaire)

#### Step 2: Match each prefix with the corresponding word

1. ex- → expand
- "Ex-" means "out of" or "away from," and "expand" means to grow outward or increase in size.

2. inter- → interstate highway
- "Inter-" means "between" or "among," and "interstate highway" refers to a road connecting different states.

3. anti- → antigravity backpack
- "Anti-" means "against" or "opposed to," and "antigravity backpack" refers to a backpack designed to counteract gravity.

4. pre- → pre-game
- "Pre-" means "before," and "pre-game" refers to the time before a game begins.

5. counter- → counterattack
- "Counter-" means "opposite" or "against," and "counterattack" refers to an attack made in response to another attack.

6. en- → enlighten
- "En-" means "make" or "cause to be," and "enlighten" means to make someone understand something.

7. extra- → extraordinary
- "Extra-" means "beyond" or "more than," and "extraordinary" means beyond the ordinary or exceptional.

8. trans- → transcontinental
- "Trans-" means "across" or "through," and "transcontinental" refers to something that spans across a continent.

9. under- → underestimate
- "Under-" means "below" or "beneath," and "underestimate" means to judge something as less important or valuable than it actually is.

10. semi- → semi-truck
- "Semi-" means "half" or "partly," and "semi-truck" refers to a truck that is only partially complete (typically requiring a trailer).

11. over- → overcompensate
- "Over-" means "above" or "too much," and "overcompensate" means to compensate excessively.

12. extra- → extraordinary
- This is already matched in step 7. If there is another word starting with "extra-", it would also fit here.

#### Final Matches:
1. ex- → expand
2. inter- → interstate highway
3. anti- → antigravity backpack
4. pre- → pre-game
5. counter- → counterattack
6. en- → enlighten
7. extra- → extraordinary
8. trans- → transcontinental
9. under- → underestimate
10. semi- → semi-truck
11. over- → overcompensate
12. extra- → extraordinary

Final Answer:

\[
\boxed{
\begin{array}{ll}
1. \text{ex-} & \rightarrow \text{expand} \\
2. \text{inter-} & \rightarrow \text{interstate highway} \\
3. \text{anti-} & \rightarrow \text{antigravity backpack} \\
4. \text{pre-} & \rightarrow \text{pre-game} \\
5. \text{counter-} & \rightarrow \text{counterattack} \\
6. \text{en-} & \rightarrow \text{enlighten} \\
7. \text{extra-} & \rightarrow \text{extraordinary} \\
8. \text{trans-} & \rightarrow \text{transcontinental} \\
9. \text{under-} & \rightarrow \text{underestimate} \\
10. \text{semi-} & \rightarrow \text{semi-truck} \\
