Hi! I need some help, also when checking my answers can you tell me an easy way to remember if a sentence has an essential clause or nonessential clause? Thank you!

** My guess

12. In which sentence is the nonessential clause uppercased

A) The man LEANING AGAINST THE WALL is from the zoo.
B) The snake THAT HE IS HOLDING is not poisonous.
C) Its coloring, WHICH IS BROWN AND GREEN, allows it to hide in marshy areas. **
D) That snake SLITHERING BEHIND THE ROCK is actually harmless

13. In which sentence is the essential clause uppercased

A) Eve's sister, WHO LOVES OPERA, oo her to a performance
B) Eve, HOLDING HER PROGRAM, waited for the curtain to go up
C) The soprano, VISITING FROM CANADA,had long black hair.
D) The person WHO SELLS SOUVENIRS is in the lobby. **

To determine if a sentence has an essential or nonessential clause, you need to consider the meaning and relevance of the clause to the overall sentence.

An essential clause, also known as a restrictive clause, provides essential information that is necessary for understanding the sentence's meaning. This type of clause cannot be omitted without changing the meaning of the sentence. Essential clauses are not set off by commas.
On the other hand, a nonessential clause, also known as a nonrestrictive clause, provides additional information that is not necessary for understanding the sentence's meaning. This type of clause can be omitted without changing the meaning of the sentence. Nonessential clauses are set off by commas.

Now let's analyze the sentences you shared:

12. In which sentence is the nonessential clause uppercased?

A) The man LEANING AGAINST THE WALL is from the zoo.
The clause "LEANING AGAINST THE WALL" is describing the man, but it does not provide essential information. If we remove the clause, the sentence still makes sense. So, this is an example of a nonessential clause.

B) The snake THAT HE IS HOLDING is not poisonous.
The clause "THAT HE IS HOLDING" is essential because it provides crucial information about the snake being referred to. Without the clause, the sentence would lack clarity. So, this is not an example of a nonessential clause.

C) Its coloring, WHICH IS BROWN AND GREEN, allows it to hide in marshy areas.
The clause "WHICH IS BROWN AND GREEN" provides additional information about the coloring of "it". If we remove the clause, the sentence will still convey the main idea. Therefore, this is an example of a nonessential clause.

D) That snake SLITHERING BEHIND THE ROCK is actually harmless.
The clause "SLITHERING BEHIND THE ROCK" is describing the snake, but it is not essential for understanding which snake is being referred to. If we remove the clause, the sentence still makes sense. So, this is an example of a nonessential clause.

Based on the analysis, the correct answer is option C) Its coloring, WHICH IS BROWN AND GREEN, allows it to hide in marshy areas.

13. In which sentence is the essential clause uppercased?

A) Eve's sister, WHO LOVES OPERA, took her to a performance.
The clause "WHO LOVES OPERA" provides essential information about Eve's sister. Without the clause, the sentence would lack clarity. So, this is not an example of an essential clause.

B) Eve, HOLDING HER PROGRAM, waited for the curtain to go up.
The clause "HOLDING HER PROGRAM" is describing Eve, but it is not essential for understanding who Eve is. If we remove the clause, the sentence still conveys the main idea. So, this is an example of a nonessential clause.

C) The soprano, VISITING FROM CANADA, had long black hair.
The clause "VISITING FROM CANADA" provides additional information about the soprano. If we remove the clause, the sentence will still make sense. Therefore, this is an example of a nonessential clause.

D) The person WHO SELLS SOUVENIRS is in the lobby.
The clause "WHO SELLS SOUVENIRS" provides essential information about the person being referred to. Without the clause, the sentence would lack clarity. So, this is an example of an essential clause.

Based on the analysis, the correct answer is option D) The person WHO SELLS SOUVENIRS is in the lobby.

I hope this explanation helps you understand the concept of essential and nonessential clauses better. If you have any more questions, feel free to ask!
