Which of the following sentence correctly follows the rules of punctuation and

capitalization?
There are two main sources of water pollution: Sewers and factories
There are two main sources of water pollution: sewers and factories
There are two main sources of water pollution; Sewer and factories
There are two main sources of water pollution; sewers and factories

None is correct because they all lack periods at the end.

However, if a period were used, then the second sentence would be correct.

You are welcome. :-)

Which of the following sentence correctly follows the rules of punctuation and capitalization?

A. There are two main sources of water pollution: Sewers and factories B. There are two main sources of water pollution: sewers and factories C. There are two main sources of water pollution; Sewer and factories D. There are two main sources of water pollution; sewers and factories

The sentence that correctly follows the rules of punctuation and capitalization is:

"There are two main sources of water pollution: sewers and factories."

To determine this, let's break down the options and explain the rules:

Option 1: "There are two main sources of water pollution: Sewers and factories."
- The word "Sewers" is capitalized. However, in this context, it should not be capitalized unless it is a proper noun. In this case, "sewers" is not a proper noun, so it should be lowercase. Therefore, this option doesn't follow the rules correctly.

Option 2: "There are two main sources of water pollution: sewers and factories."
- The word "sewers" is correctly lowercase as it is not a proper noun.
- The colon (:) is used properly to introduce the list of sources.
- The words "sewers" and "factories" are correctly pluralized to match the subject of the sentence.
- This option follows the rules of punctuation and capitalization correctly.

Option 3: "There are two main sources of water pollution; Sewer and factories."
- The semicolon (;) is used incorrectly here. A colon (:) would be appropriate when introducing a list.
- The word "Sewer" is capitalized but should be lowercase, just like in option 1.
- This option doesn't follow the rules of punctuation and capitalization correctly.

Option 4: "There are two main sources of water pollution; sewers and factories."
- The semicolon (;) is used incorrectly here. A colon (:) would be appropriate when introducing a list.
- The words "sewers" and "factories" are correctly lowercase and pluralized.
- This option doesn't follow the rules of punctuation and capitalization correctly.

Therefore, option 2 is the correct sentence that follows the rules of punctuation and capitalization.

Thank you, and yes there's supposed to be a period at the end.
