The last sentence is correct: The restoration of his ’67 Mustang convertible was not as difficult as yours
In the first sentence, Mr. Carter’s is right but your’s is wrong
In the second sentence, student’s is wrong but one’s is right
Anything you accomplish does not come with ease it's going to take hard work
The correct options are "The sentence contains a restrictive clause", and "Only the lucky children got presents".
A restrictive clause is <u>the use of an adjective to modify a certain word inside a sentence</u>. This modification has to be <u>crucial in determining the meaning of the entire phrase</u>.
In this case, the word "lucky" acts as the modifier for "the children". It's a restrictive clause because it tells us that only the lucky children got presents. The word "lucky" is restricting the intended meaning of the phrase by excluding unlucky children.
Hope this helps!
