[Vocabulary] Need help with a linking word.

[mscola]

Hello

I am doing some exercises in my proficiency book (Objective Proficiency) and one of the exercises is "fill in the blank". There is an article about socks and I do not understand why my answer is considered to be wrong:

Yet socks are possibly the most ancient of human inventions - an Egyptian mummy's knitted socks are arguably the oldest surviving examples, some hand-sewn versions may date back to the Bronze Age.

According to the book, the correct answer should be but/while/whilst/although.

What is wrong with using "some"?

Thanks a lot for your help.

Massimo

The sentence as written contains a comma splice. If the comma were replaced with a semicolon or a period ("full stop" in BrE), you'd have one or two correct sentences.

The correct answer words are all conjunctions, words which can join two clauses. "Some" isn't.
