TLDR: The common noun is "sandwich".
A common noun is a person, place, or thing that isn't being described specifically. A proper noun is a person, place, or thing that is being described specifically. For example:
A house (CN), versus The White House (PN)
A Meatball Marinara (PN) versus a footlong sub (CN)
New York City (PN) versus The Big Apple (PN) versus a city (CN)
Proper nouns can typically be identified by being capitalized, however this may not always be the case! However, in this example, it is.
Start by looking for nouns - this sentence contains two, Carlene and sandwich. A sandwich is a common noun because it is generic, whereas Carlene is being specific - we're talking about a particular girl who happens to like sandwiches. Therefore, "sandwich" was the common noun in this sentence.
Hope this helps!
For a child his/her
childhood is a precious time in terms of memories as well as moral and social
training. When a child is abandoned he/she is practically denied the basic
training which was their birth right. This sometimes results in the form of an
unstable adult who later in their lives can be emotionally dark and will not be able to be the
citizen which they need to be. In the worst case scenario such a child can turn
towards criminal activities as he/she can held the whole society responsible
for the negligence.
