Answer:
Q9 - The artist is ridiculing John VII by comparing him to the soldiers who taunted Jesus.
Q10 - At one point, Spain was part of the Islamic world.
Q11 - Ornate and patterned.
Explanation:
Q9 - By using the action of scrubbing the icon with the long pole and a sponge, having in mind that the same method was used in the image is making a comparison to the soldiers. The point is that giving vinegar to Jesus in order for him to suffer isn't considered a good action, therefore being the reason why John VII is ridiculed.
Q10 - If the art shown has Islamic roots and it's still preserved, it shows that Spain at some point embraced this specific culture and was, then, part of the Islamic world.
Q11 - The gold inlay is the key to understand this question. The gold makes it ornate and the typical style that is preserved shows that there's a pattern involved.
