B.) A bicycle
C.) An atlas
D.) A plastic human skeleton

I'm not really sure what the answer is

Do you mean MODEL? Check the definition of model.

To determine which of the given options is not a modal, we need to first understand what a modal is. A modal refers to a type of auxiliary verb that is used to express possibility, necessity, ability, permission, or logical deduction.

Now, let's analyze each option:

A.) An ant farm: This is not a modal because it does not function as an auxiliary verb. It is a noun phrase referring to a container for keeping ants.

B.) A bicycle: Similar to option A, a bicycle is also a noun and not a modal.

C.) An atlas: Again, an atlas is a noun, not a modal.

D.) A plastic human skeleton: Like the previous options, a plastic human skeleton is a noun and does not serve as a modal.

Based on this analysis, we can conclude that none of the given options are modals. Therefore, the answer to the question "Which of the following is not a modal?" is: All of the options (A, B, C, and D) are not modals.
