In the previous question, Question #257, we looked at the image of a distant star as it passed directly behind a gravitational lens, so that the star, the lens, and the observer were at one point co-linear. This question involves what happens when the distant star passes behind the gravitational lens, but is slightly above theh line defined by the observer and the center of the lens.
You may select your list of answers, in order of their appearance as the star moves from left to right across you computer screen, from the "typical" sequence of pictures shown reproduced from the previous question:
| (a) | 
| (b) | 
| (c) | 
| (d) | 
|
| (e) | 
| (f) | 
| (g) | 
| (h) | 
|
| (i) | 
| (j) | 
| (k) | 
| (l) | 
|
| (m) | 
| (n) | 
| (o) | 
|
Oh, yes, one more detail. You may have to invent some other "look" for the image as it passes behind the lens, other than the exact ones given above.
