[Grammar] take A for B, take sth for granted

[maoyueh]

1. She looks so young that I took her for your sister.
2. She took his willingness to help for granted.

In the sentences above, are the phrases "for your sister" and "for granted" complements or adverbs? Thank uou very much.

I don't know, but I do know that the collocation 'take for granted' has no connection with the 'take for' in the first sentence.
