Question

correct the sentence by adding a comma or commas. (note: in this skill, serial commas are not optional.) although philo t. farnsworth grew up without electricity he went on to invent the television.

Explanation:

The sentence starts with a dependent clause ("Although Philo T. Farnsworth grew up without electricity") followed by an independent clause ("he went on to invent the television"). When a dependent clause is at the beginning of a complex sentence, a comma should separate it from the independent clause. So we add a comma after "electricity".

Answer:

Although Philo T. Farnsworth grew up without electricity, he went on to invent the television.
