2) Peat bogs are wetlands that contain acidic water and large deposits of compressed, dead plant material known as peat. Peat bogs are typically shallow and punctuated by areas of semi-dry land. Slabs of peat can be cut from the bog and used in agriculture or dried and then burned as fuel. Peat was a significant fuel in some pre-industrial societies, especially those that lacked plentiful firewood. Peat bogs can preserve dead plants and animals because the acidic water prevents rotting and decomposition. Importantly, some of the best-preserved early human remains have been discovered in peat bogs.

I think number two is Importantly, some of the best-preserved early human remains have been discovered in peat bogs.

Yes, for both of your answers.

1) Out of the given options, the correct punctuation is:

After you sign the agreement, it is too late, of course, to change your mind.

The correct punctuation includes commas before and after the phrase "of course," as it provides additional information that can be omitted from the sentence without affecting its basic meaning. The final comma is used to separate the introductory clause "After you sign the agreement" from the main clause "it is too late to change your mind."

2) The sentence that contains an opinion is:

B. Peat was a significant fuel in some pre-industrial societies, especially those that lacked plentiful firewood.

This sentence expresses a subjective evaluation or belief about the significance of peat as a fuel in pre-industrial societies. The use of "significant" indicates a subjective judgment rather than a verifiable fact. The other sentences mentioned in options A, C, and D mainly present factual information about peat bogs and their characteristics.
