In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Let me give you an example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Passage: The painted surface is divided into quarters horizontally and sevenths vertically; this grid is used to organise the elaborate grouping of characters, and was a common device at the time. Velázquez presents nine figures—eleven if the king and queen's reflected images are included—yet they occupy only the lower half of the canvas.According to López-Rey, the painting has three focal points: the Infanta Margaret Theresa, the self-portrait and the half-length reflected images of King Philip IV and Queen Mariana. In 1960, the art historian Kenneth Clark made the point that the success of the composition is a result first and foremost of the accurate handling of light and shade:
Each focal point involves us in a new set of relations; and to paint a complex group like the Meninas, the painter must carry in his head a single consistent scale of relations which he can apply throughout. He may use all kinds of devices to help him do this—perspective is one of them—but ultimately the truth about a complete visual impression depends on one thing, truth of tone. Drawing may be summary, colours drab, but if the relations of tone are true, the picture will hold.
Velázquez further emphasises the Infanta by his positioning and lighting of her maids of honour, whom he sets opposing one another: to left and right, before and behind the Infanta. The maid to the left faces the light, her brightly lit profile and sleeve creating a diagonal. Her opposite number creates a broader but less defined reflection of her attention, making a diagonal space between them, in which their charge stands protected.A further internal diagonal passes through the space occupied by the Infanta. There is a similar connection between the female dwarf and the figure of Velázquez himself, both of whom look towards the viewer from similar angles, creating a visual tension. The face of Velázquez is dimly lit by light that is reflected, rather than direct. For this reason his features, though not as sharply defined, are more visible than those of the dwarf who is much nearer the light source. This appearance of a total face, full-on to the viewer, draws the attention, and its importance is marked, tonally, by the contrasting frame of dark hair, the light on the hand and brush, and the skilfully placed triangle of light on the artist's sleeve, pointing directly to the face.
From the figure of the artist, the viewer's eye leaps again diagonally into the pictorial space. Another man stands, echoing and opposing the form of the artist, outside rather than inside, made clearly defined and yet barely identifiable by the light and shade. The positioning of such an area of strong tonal contrast right at the rear of the pictorial space is a daring compositional tactic. The shapes of bright light are similar to the irregular light shapes of the foreground Maid of Honour, but the sharply defined door-frame repeats the border of the mirror.
Answer:
What is the name of the person whose features are not sharply defined?
