I don't know if i should be embarrassed for not knowing what is a fruit and what is a vegetable.

1. Tomato. Biologically a fruit, culinarily widely used as a vegetable.

2. Carrot (whole plant shown). The top is just edible leaves, that is the most definite vegetable. The root is considered a root vegetable and is used as a vegetable.

3. Red onions, one of them is sprouted. All parts are edible (to humans, they are toxic to many other species including dogs and cats). Same situation as with the carrot.

4. Banana or plantain. It's botanically a fruit. Both are the same species and the name depends on whether the cultivar is used as a fruit (sweet, eaten raw or used in desserts) or more as a vegetable (more starchy and used mostly for cooking). I don't bananas well enough to discern the cultivar, so I don't know.

5. Grapes. Botanically a fruit. They are also used as a fruit and the most uambigously not a vegetable of all of them.

6. Corn, seems to be sweet corn. Again botanically a fruit (strictly speaking the individual corns are the seeds). Shown with husks which are also technically edible but you'll probably need to deep fry them to make chips or something. Assuming we are just going with the corn they are considered a vegetable.

7. Avocado. Botanically a fruit. Eaten raw like a fruit. Used in salads and condiments more like a vegetable? The Wikipedia article avoids making any judgment on whether it's a vegetable. So dunno.

8. Mr. Potato Head from Toy Story. A CGI rendering of a plastic toy. Mr. Potato Head should not be eaten. But also he is presumably based on a potato which is considered a root vegetable.

9. Eggplant. Botanically a fruit, culinarily considered a vegetable.

I hope this left you even more confused because it certainly did for me. Also I have no idea what the correct answers are for the quiz, and I got tired of trying different combinations.

Humanity doesn't seem to have a universally accepted definition for that. Originally, colloquially, all the plants were vegetables that had edible parts. Later fruits and vegetables had their own category, even though many of the fruits are not true fruits, some vegetables are actually fruits etc. It's a mess, as colloquial language usually is.
