Simple, Compound And Run-on Sentences! Quiz

Explanation
The two complete sentences are not joined correctly (with either a comma and conjunction OR a semicolon)

Explanation
The given sentence is a simple sentence because it contains only one independent clause. It states a fact about common dolphins, that they live in warm waters and swim in large schools. There are no additional clauses or conjunctions that would make it compound or run-on.

Explanation
The given statement states that porpoises are similar to dolphins and they generally live in cooler water. This implies that there are two separate ideas being presented in the sentence, making it a compound sentence.

Explanation
The given statement describes two characteristics of dolphins: their beak-like snouts and their method of swimming by moving their tails up and down. It is a simple sentence because it consists of a single independent clause and does not contain any additional clauses or conjunctions.

Explanation
This sentence is a simple sentence because it consists of one independent clause. The subject "Dolphins" and the verb "use" are clearly stated, and the sentence expresses a complete thought. The phrase "just like bats" provides additional information, but it does not create a compound sentence as it is not joined with a coordinating conjunction. Therefore, the sentence is simple.

Explanation
The given statement is a run-on sentence because it contains two independent clauses that are not properly joined or punctuated. The first clause "Porpoises can swim very fast" and the second clause "so they can outswim most sharks" are not separated by a coordinating conjunction or appropriate punctuation. A run-on sentence occurs when two or more independent clauses are joined together without proper punctuation or conjunctions.

Explanation
The given sentence contains two independent clauses connected by the coordinating conjunction "and." This makes it a compound sentence. Each clause can stand alone as a complete sentence, but they are joined together to show a relationship between the length and weight of bottle-nosed dolphins.

Explanation
The given sentence contains two independent clauses, "Dolphins can be easily trained" and "they are very smart mammals," which are joined by the coordinating conjunction "for." This conjunction indicates a cause-and-effect relationship between the two clauses. Therefore, the sentence is compound, as it consists of two related but independent thoughts connected by a coordinating conjunction.

Explanation
The given sentence is a run-on because it consists of two independent clauses ("Many people like to go on dolphin watches" and "few get to swim with the dolphins") that are not properly connected or separated. A run-on sentence occurs when two or more independent clauses are joined together without appropriate punctuation or conjunctions. In this case, the sentence could be corrected by adding a coordinating conjunction like "but" or by separating the clauses into two separate sentences.

Explanation
The given statement is a simple sentence because it consists of one independent clause. It states a fact about dolphins and porpoises saving people and allowing them to ride on their backs. There are no additional clauses or conjunctions present in the sentence.
