Consider the following pairs:

Sea	Bordering country
1. Adriatic Sea	Albania
2. Black Sea	Croatia
3. Caspian Sea	Kazakhstan
4. Mediterranean Sea	Morocco
5. Red Sea	Syria

Which of the pairs given above are correctly matched?

The correct answer is 1, 3 and 4 only.

Let us analyze each pair individually to determine whether the sea is correctly matched with its bordering country:

1. Adriatic Sea – Albania: Correctly Matched
The Adriatic Sea is a body of water separating the Italian Peninsula from the Balkan Peninsula. Albania is situated on the southeastern coast of the Adriatic Sea, so it directly borders it.

2. Black Sea – Croatia: Incorrectly Matched
The Black Sea is bordered by six countries: Turkey, Bulgaria, Romania, Ukraine, Russia, and Georgia. Croatia does not border the Black Sea; rather, Croatia lies along the Adriatic Sea.

3. Caspian Sea – Kazakhstan: Correctly Matched
The Caspian Sea is the world's largest inland body of water. It is bordered by five countries: Kazakhstan, Russia, Azerbaijan, Iran, and Turkmenistan. Thus, Kazakhstan borders the Caspian Sea.

4. Mediterranean Sea – Morocco: Correctly Matched
Morocco is located in North Africa and has coastlines on both the Atlantic Ocean and the Mediterranean Sea (to its north).

5. Red Sea – Syria: Incorrectly Matched
The Red Sea is bordered by Egypt, Sudan, Eritrea, Djibouti, Saudi Arabia, and Yemen. Syria is located further north in the Middle East and borders the Mediterranean Sea, not the Red Sea.

Therefore, pairs 1, 3, and 4 are correctly matched.
