Question

Read the sentence.

Physics teacher
a. a. Michelson measured the speed of light in 1878.
Which word or phrase is the complete predicate?
A) the speed of light
B) physics teacher
a. a. Michelson
C) measured the speed of light in 1878
D) in 1878

Answer 1

C is the correct answer, because a 'predicate' is a verb with everything that accompanies it, such as objects, adverbial modifiers, etc. And A, B, or D don't even have a verb in them. 

Answer 2

The correct option is letter C) measured the speed of light in 1878.

Step-by-step explanation:

A predicate consists of a verb or a verb phrase that offers information about a subject. In other words, a predicate is everything in a structure (verb, objects, complements) that is not the subject. The subject is what the sentence is about, its topic. In the sentence "Michelson measured the speed of light in 1878," Michelson is the subject, the person this sentence is about. The rest of the sentence is the complete predicate:

measured - verb

the speed of light - object

in 1878 - adverbial phrase of time
