13 = A culture consist of a group of people with similar beliefs, political and religious opinions, and a culture of food and clothing.

Here's what I wrote, "A culture is a group of people who share a similar way of life.  Often they share the same beliefs and opinions (political and religious), dress similarly and even eat similar foods.  They also share a way of seeing and  representing things.  Sometimes a culture is part
of a civilization however a civilization is usually tied to a specific geographic region. "

15 = A culture and civilization are the factors that influence a style.

The following is a quote from the website,
"Style is influenced by culture and civilization."
In your answer you only reversed the order of the words.

> The physical and formal characteristics help define a style.

In your section you lifted a section directly from the passage I wrote, "physical or formal characteristics."

> A style can also help identify the work’s culture and civilization.

Same thing here, "work's culture or civilization."
