Your

A. "Her teacher had shown her one of Kandinsky’s most famous abstract works, 'Colour Studies: Squares and Concentric Circles,' when she first began taking classes from him."

B. "He loved her style so much that he wanted her to sell her pieces...And even though he understood, he’d become increasingly frustrated; he desperately wanted to show her work to the greater public."

C. "Marcus himself owned one that featured his friends’ work in addition to his own, but since his gallery was booked through the rest of year with various showings, he could not feature Ariana’s artwork anytime soon."

D. "Not a single paintbrush lay near her; the young artist preferred to use alternative painting tools, like string and sponges."
