[Q]: For combination of grace, dramatic strength, and clearness in technique this picture would be difficult to surpass. There is nothing finicky about it; it tells its story with vivid directness. As a background to the figure Mrs. Rix Nicholas has set a piece of antique tapestry, so that the trees on either side lean in arch-wise over the head, the face and shoulders stand out clearly against an expanse of sky, and behind the body and limbs extends a countryside full of towers and rivers and trees. The quaint conventionality of this background accords exactly with the late eighteenth-century costume, all sprigged with roses and heliotrope; and the whole mass of detail harmonies [sic] perfectly with the type of the model's face. It is a cold, selfish face. The artist has brought out with revealing strokes an expression of vindictive malice which is for the moment resting there; and the hands, the fingers of one grasped tightly by the other, give a clear indication of nervous tension within. The treatment of flesh tones and the general arrangement, drawing attention gently but not too obtrusively to the columbines scattered on the polished floor—those are excellent. While she exhibited many of the Australian works completed before arriving in France, she was also creating many new works, including illustrations and portraits of traditional life and costume, produced during a summer in Brittany. In 1926, Rix Nicholas was again included in London's Royal Academy of Art exhibition, where one of her Brittany paintings, Le Bigouden, was hung. She also appeared at the Société Nationale des Beaux-Arts Spring exhibition in Paris, in which she had eight works, a very large number for a single artist. The Société not only hung many of her paintings and drawings: she was also elected an Associate to the organisation in that year.At the end of 1926, Rix Nicholas and Dorothy Richmond together returned to Australia. Energised by her success, Rix Nicholas purchased a car, filled its rear compartment with painting equipment, and the pair set out to paint the landscape, ranging from Canberra and the Monaro plains to the south, up into central Queensland. This included a publicity-attracting occasion where she painted figures on the beach at Bondi, reported by various publications including Australian magazine, The Home.
[A]: What is the full name of the person who paired with Rix Nicholas to set out and paint the landscape?

[Q]: In 1933, Freya Roth is a young German girl engaged to a Nazi party member. When she realizes the true nature of his political views she breaks the engagement and turns her attention to anti-Nazi Martin Breitner. Her father, Professor Roth, does not abide by the attitude of the new order towards scientific fact. Though his stepsons Erich and Otto eagerly embrace the regime, Professor Roth's reluctance to conform leads at first to a boycott of his classes and eventually to his arrest and a sentence of forced physical labor. His wife is permitted a five-minute visit in which the professor urges her to take Freya and her younger brother and leave the country. He dies soon after. Freya is kept from leaving by Nazi officials suspicious of her father's work. She reunites with Martin and together they attempt to escape through a mountain pass. A squad reluctantly led by her former fiancee gives chase and Freya is fatally wounded, dying in Martin's arms just after they cross the border. Later, Erich and Otto are informed of their sister's death. Erich responds with anger towards Martin.  Otto, however, experiences an epiphany, and flees their once-happy home, rejecting the Nazis and their cruel doctrine.
[A]:
Who is Erich and Otto's stepfather?
