Respuesta :
I think it would be visualize because that would be the only one that makes sense.
Answer:
If the suffix -ize means “cause to be,” the bolded word that means “cause to be seen” is visualize.
Explanation:
As the word visualize has the suffix ize which means "cause to be" it also has the root word vis that means "to see", taking these two references we can say that we have the root word "see" and the suffix "cause to be" which lead as to the definition of "cause to be seen", besides there are some keywords in the excerpt that talks about images such as "looked like".
