The correct sentence is "They knew that it was she who created the beautiful painting," because the pronoun 'she' is used as a subject of the clause. You cannot use 'her' as a subject; it is usually used as a possessive pronoun.
The clause "it was she who created the beautiful painting" is grammatically correct because 'was' serves as the linking verb, making IT and SHE equal. So, if you are going to rephrase the sentence it would be 'She was the one who created the beautiful painting' and not 'Her was the one who created the beautiful painting'.

The author communicates feelings about love relationships by describing in detail the many sensations about his loved woman. It was a love almost crazy, desperate and like if nothing else in the world existed.
This kind of feeling is really very risky since the person centers life in that love and if love breaks or one of the couple dies simply life ends up.
Prereading means skimming through a book or chapter for main ideas, so I guess I would say True.... Thought that may be incorrect, not sure.
