Answer:
Orwell's statement that Squealer "could turn black into white is an example of an IMPLICIT description
Step-by-step explanation:
Implicit description is one which states something and from which we have to imply some ideas opinions from it. From this statement we have to imply that squealer would be able to justify to the animals of any wrong done by Napolean or other pigs.
Explicit Description is one which clearly states what it wants to state.
Example: This line about Squealer is an example of explicit description;
"Squealer easily convinced them that the veterinary surgeon in Willingdon could treat Boxer's case more satisfactorily than could be done on the farm"
