Read the last paragraph of the article.

The Incas might have failed to develop a way to represent words with symbols. Or maybe we have been underestimating them. Perhaps they had their own very special way of telling stories. We might be closer to finding that out.

How does this paragraph support the main idea of the article?
A. It highlights the idea that khipu could have been a form of language for the Incas.
B. It explains why researchers are having a hard time understanding khipu.
C. It provides evidence to support the idea that khipu have phonetic symbols.
D. It describes what each of the parts of a khipu meant for the Incas.

The answer is A

Explanation:

Because the reason why is it states specifically that the Inca's told stories like that to tell stories. Yes researchers are having a problem understanding that but because IT WAS THEIR OWN FORM OF LANGUAGE! The researchers have to continue to research it like they did with hieroglyphics to figure it out.

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.
