Answer: So basically Academic writing is a clear, concise, focussed, structured and backed up writing by evidence. It has a formal tone and style, but it is not complex and does not require the use of long sentences and complicated vocabulary. Some features are complexity, formality, precision, objectivity, explicitness, accuracy, hedging, responsibility, organization and planning. Hope this helps.
It depends.
'Mike and Mary's Pizza' is most likely a place, and a noun is a person, place, or thing. If it is a person's name, a place (such as a street name, name of a place, a city, a country, a town..) it must be capitalized. Just regular English rules.
Now, if the Mike and Mary HAD a pizza, you would not need to capitalize pizza considering it is the object. Here's an example of a sentence where you wouldn't need to capitalize pizza - "Mike and Mary's pizza was cheese." Now here's an example of where you would want to capitalize pizza - "I am headed to Mike and Mary's Pizza to get some food."
The theme is the central message in a literary work!
Hope that helped, even though it was slightly late :D
