1. It has never been more true to say that a dog is a man's best friend.

2. In response, the dog bit the intruder who was attacking his owner.

3. Last Tuesday night, a dog and his owner were asleep in their home.

4. An intruder broke into the house in the early hours of the morning.

Using the sentences above, which of the following sentence orders best forms an organized, logical paragraph?

Option A is correctly punctuated. It uses the possessive form "student's" to indicate that the friend belongs to the working student.

The possessive apostrophe is placed after "student" and before the "s" to indicate that the friend is singular and not plural.

A dangling modifier is a phrase or clause that does not logically modify any word in the sentence. Example: "My brother had an old truck that sat by the garage that needed paint." The phrase "that needed paint" is a dangling modifier because it does not clearly modify any word in the sentence.

It is unclear whether it is the truck or the garage needed paint.

These prefixes mean "not" or "opposite of." "Mis-" means "wrongly" (like in "misunderstand"), so it does not fit.

The sentence "He liked to cook at home, but she preferred to eat at restaurants." correctly uses a compound sentence structure. It consists of two independent clauses "He liked to cook at home" and "she preferred to eat at restaurants" joined by the coordinating conjunction "but".

In the given sentence, "the class" is a singular noun and requires a singular possessive pronoun. "Its" is the correct form of the possessive pronoun "it" to use with a singular noun, as opposed to "it's," which is a contraction of "it is" and would not be appropriate in this context. "They're" is a contraction of "they are" and would not be appropriate because "class" is singular, not plural.

This sentence presents a specific statistic that may not be common knowledge and is not the author's original idea, so it requires a citation to give credit to the source of this information. A citation is needed to show where this statistic came from, who conducted the study, and when it was conducted. Therefore, option C is the correct answer.

A complex sentence is one that contains an independent clause and at least one dependent clause.

In Choice C: "Since time was running short, I hurriedly brushed my teeth while breakfast was warming up," we have an independent clause: "I hurriedly brushed my teeth," and a dependent clause: "Since time was running short." The dependent clause cannot stand alone as a complete sentence, so it depends on the independent clause for its meaning. This combination of an independent and dependent clause makes Choice C a complex sentence.

The other choices are not complex sentences because they either lack a dependent clause or do not have the same level of complexity in their structure.

This sentence is spelled correctly. The other choices have mistakes: "hear" instead of "here," "price" instead of "prize," and "harestyles" instead of "hairstyles."

The Krebs cycle, part of cellular respiration, happens in the mitochondria. Fermentation and glycolysis happen in the cytoplasm, and photosynthesis occurs in plant cells' chloroplasts.

Choice B: "Whenever the boys played in the rain, they came home with muddy clothes."

This is a complex sentence. "Whenever the boys played in the rain" is a dependent clause because it cannot stand alone as a complete thought, and "they came home with muddy clothes" is an independent clause because it can stand alone. The sentence does not contain two independent clauses joined by a coordinating conjunction (which would make it a compound sentence).

Choice D: "She wanted to go to the beach after she left work."

This is also a complex sentence. "She wanted to go to the beach" is an independent clause, and "after she left work" is a dependent clause because it cannot stand alone as a complete sentence.

To clarify:

• Complex sentence: Contains an independent clause and at least one dependent clause.
• Compound sentence: Contains two independent clauses joined by a coordinating conjunction (like "and," "but," or "or").

Thus, both B and D are complex sentences, but B is the most accurate answer in many tests as it clearly demonstrates the use of a dependent clause ("Whenever the boys played in the rain") followed by an independent clause.
