Of the following sentences, which is a run-on sentence?

a. Carbon dioxide is, in turn, excreted by plants and it is produced by a variety of human activities, such as the burning of hydrocarbon fuels.

b. Along with carbon dioxide, water vapor and other waste products can accumulate in the atmosphere this creates a kind of barrier to the reflection of solar energy.

c. Some of the solar energy would otherwise bounce off the earth's surface and escape through the atmosphere.

d.  If enough carbon dioxide and other materials accumulate, scientists fear that our environment will become like a greenhouse.

I chooes C is my answer right?

Ammm so maybe B is the answer?

Yes, B.

Here's where the two sentences run together:
"… in the atmosphere this creates a kind of barrier …"

Yes I understand now thank you 🙏🏻

Not C. That's a perfectly good simple sentence with one subject (Some) and a compound verb (would bounce, escape)

Find the one where a second sentence starts in the middle, but there's no period and capital letter to separate the two sentences.

Can you help me with this ?

Which of the following sentences is grammatically correct?

a. Following a strict low-fat diet weight loss can become a reality.

b. Following a strict low-fat diet your reality can be weight loss.

c.If you follow a strict low-fat diet, weight loss can become a reality.

d.When you follow a strict low-fat diet weight loss can become a reality.

I choose C but some of my classmates say D is the correct one.
I choose C because of IF and the (,) between 2 sentences

You’re right. The correct sentence is C — and yes, because the comma is there. (D needs a comma.)

No, your answer is incorrect. Sentence C is not a run-on sentence. A run-on sentence is a sentence that contains two or more independent clauses without proper punctuation or conjunctions to connect them. Let's analyze each sentence to find the correct answer:

a. "Carbon dioxide is, in turn, excreted by plants and it is produced by a variety of human activities, such as the burning of hydrocarbon fuels." This sentence is not a run-on sentence because it uses proper punctuation (comma) to separate the two independent clauses.

b. "Along with carbon dioxide, water vapor and other waste products can accumulate in the atmosphere this creates a kind of barrier to the reflection of solar energy." This sentence is a run-on sentence because it contains two independent clauses ("water vapor and other waste products can accumulate in the atmosphere" and "this creates a kind of barrier to the reflection of solar energy") without proper punctuation or conjunctions to connect them.

c. "Some of the solar energy would otherwise bounce off the earth's surface and escape through the atmosphere." This sentence is not a run-on sentence because it only contains one independent clause.

d. "If enough carbon dioxide and other materials accumulate, scientists fear that our environment will become like a greenhouse." This sentence is not a run-on sentence because it uses proper punctuation (comma) and a conjunction (if) to connect the two independent clauses.

Therefore, the correct answer is b. "Along with carbon dioxide, water vapor and other waste products can accumulate in the atmosphere this creates a kind of barrier to the reflection of solar energy."
