Explanation

The food item was fantastic on the menu card.

The preposition on is used when referring to a food item

On the menu: This means the item is listed on the physical or digital menu.

Explanation

Everything is good on the menu

We use "on the menu" when talking about items listed in a menu.  

So, the correct preposition is "on", not "in", "at", or others.

Explanation

When two subjects are joined by "as well as", the verb agrees with the first subject.  

Here, "Father" is singular, so the verb should be "was".

Explanation

The correct sentence is: "She told the doctor that he had not been sleeping for the previous day." 

The error is the omission of the definite article "the" before "previous day."

The word "previous" is an adjective that needs a determiner like "the" when referring to a specific, singular day. 

Explanation
