1. Question 4 is based on this passage.
X-ray examination of a recently discovered painting—judged by some authorities to be a self-portrait by Vincent van Gogh—revealed an underimage of a woman’s face. Either van Gogh or another painter covered the first painting with the portrait now sec, on the surface of the canvas. Because the face of the woman in the underimage also appears on canvases van Gogh is known to have painted. the surface painting must be an authentic self-portrait by van Gogh.

4. The conclusion is properly drawn if which of the following is assumed?

If a canvas already bears a painted image produced by an artist, a second artist who uses the canvas to produce a new painting tends to be influenced by the style of the first artist.

Many painted canvases that can be reliably attributed to van Gogh contain underimages of subjects that appear on at least one other canvas that van Gogh is known to have painted.

Any painted canvas incorrectly attributed to van Gogh would not contain an underimage of a subject that appears in authentic paintings by that artist.

A painted canvas cannot be reliably attributed to an artist unless the authenticity of any underimage that painting might contain can be reliably attributed to the artist.

A painted canvas cannot be reliably attributed to a particular artist unless a reliable x-ray examination of the painting is performed.

2. Question 3 is based on this passage.
That sales can be increased by the presence of sunlight within a store has been shown by the experience of the only Savefast department store with a large skylight. The sky light allows sunlight into half of the gore, reducing the need for artificial light. The rest of the store uses only artificial light. Since the store opened two years ago, the departments on the sunlit side have had substantially higher sales than the other departments.
3.Which of the following, if true. most strengthens the argument?

On particularly cloudy days, more artificial light is used to illuminate the part of the store under the skylight.

When the store is open at night, the departments in the part of the store under the skylight have sales that are no higher than those of other departments.

Many customers purchase items from departments in both parts of the store on a single shopping trip.

Besides the skylight, there are several significant architectural differences between the two parts of the store.

The departments in the part of the store under the skylight are the departments that generally haw the highest sales in other stores in the Savefast chain.
