alloy contains

Ms.Sue is wrong because This alloy is the simple subject.

To identify the simple subject and simple predicate in a sentence, we need to understand their definitions:

1. Simple Subject: It is the main noun or pronoun in the sentence. It represents the person, place, thing, or idea that the sentence is about.
2. Simple Predicate: It is the main verb or verb phrase in the sentence. It describes the action or state of the subject.

Let's break down the given sentence:

"This alloy contains a mixture of iron and carbon."

Simple Subject: The main noun in this sentence is "alloy." It is the subject because the sentence is discussing the alloy.

Simple Predicate: The main verb phrase in this sentence is "contains a mixture of." It describes the action of containing a mixture of iron and carbon.

Therefore, the simple subject is "alloy," and the simple predicate is "contains a mixture of."
