To the right, there's a blank white area. In the center, there's a main graphic composed of red and blue circles and letters. After the text block on the left disappears, what changes occur to the central graphic?
Options:
A) Disappeared
B) Covered by the yellow overlay
C) Shrunk
D) Moved slightly to the bottom left, and new parts appear in the screen
E) Moved to the right

Question: K and y circled in green on a white background

Here are selected frames. They are located at 378.9s,980.5s,1590.5s,1718.0s,1726.3s,1838.3s,2195.7s,2424.5s.

<think>From the provided frames, I can observe that the letters 'K' and 'y' are circled in green on a white background. When the middle part of the text is covered by a yellow and green overlay, the letters 'K' and 'y' are no longer visible. This suggests that the letters have been covered by the overlay. Based on the options provided, the correct answer is that the letters 'K' and 'y' disappeared when the middle part of the text was covered by a yellow and green overlay.</think>

Question: circuit diagram shrinks

Here are selected frames. They are located at 185.9s,359.8s,1329.6s,1335.5s,1918.1s,2223.1s,2356.6s,2424.5s.

<think>From the provided frames, it is evident that the circuit diagram in the upper left section remains visible and does not shrink or disappear when the text information in the middle left and bottom left sections almost disappears. Instead, the text information seems to fade out, leaving the circuit diagram more prominent. Therefore, the correct answer is that the circuit diagram in the upper left section enlarges.</think>
