Answer:
True.
Explanation:
A research paper turned in for credit is indeed the final product.
The answer is a. President.
The word President is the predicate nominative here, also known as predicate noun.
A predicate noun is a word which renames the noun that has been mentioned in the sentence. In this case Franklin Roosevelt is the noun that has been renamed as "President", which makes it the answer to the question.
Another example in : My brother's favourite food is pizza.
The predicate nominative in the sentence is Pizza. because that is the word that is replacing the earlier mentioned noun, which was "food".
C. These early doughnuts were found in prehistoric Native American ruins.
C is the best answer. A tradition is something that has been around for a while. Option C says that doughnuts were found in prehistoric Native American ruins which means that they have been around for a long long time. Option D is not a good choice because it doesn't say anything about donuts, it's only about bread. The other options do not indicate that they have been around for a significant portion of time.
