Sentence Combining

Which sentence correctly combines these two ideas using the relative pronoun 'who'?

The girl won the science fair. She is my best friend.

• The girl who is my best friend won the science fair.

• The girl, she is my best friend, won the science fair.

• The girl is my best friend and won the science fair.

• The girl won the science fair, who is my best friend.

Answer explanation

This sentence correctly uses the relative pronoun 'who' to introduce a clause that identifies which girl won. The other options are grammatically incorrect or create a comma splice.

Which sentence best uses a subordinating conjunction to show that finishing homework is the reason you can play games? Sentences: I finished my homework. I can play video games.

• Although I finished my homework, I can play video games.

• Because I finished my homework, I can play video games.

• I finished my homework, yet I can play video games.

• I finished my homework until I can play video games.

Answer explanation

The subordinating conjunction 'Because' correctly shows a cause-and-effect relationship. 'Although' and 'yet' show contrast, and 'until' indicates a time limit, none of which fit the intended meaning.

Which sentence correctly uses a nonessential appositive to combine these ideas?

My favorite snack is pizza. It is a classic choice.

• My favorite snack, pizza, is a classic choice.

• My favorite snack is pizza a classic choice.

• My favorite snack pizza, is a classic choice.

• My favorite snack is pizza, it is a classic choice.

Answer explanation

The appositive 'pizza' renames 'snack' and is correctly set off by commas because it provides nonessential (extra) information. The other options have incorrect or missing punctuation.

Which sentence best combines these ideas using a participial phrase?

The student was texting in class. He was caught by the teacher.

• The student was texting in class, and he was caught by the teacher.

• Texting in class, the student was caught by the teacher.

• The student, who was texting in class, was caught by the teacher.

• The student was caught by the teacher because he was texting in class.

Answer explanation

This option correctly uses the present participial phrase 'Texting in class' to modify 'the student' and combine the ideas concisely. The other options use different, less concise structures.

True or False: In the sentence 'My three best friends—Leo, Mia, and Sam—are all coming to my party,' the dashes are used correctly to add emphasis to the list of friends.

• True

• False

Answer explanation

This is true. Dashes can be used in place of commas to set off a nonessential element, like an appositive. They are particularly useful for adding emphasis or when the element itself contains commas, as this list does.

Which is the most logical and well-structured way to combine these two sentences?

The team practiced for weeks. They lost the championship game.

• The team practiced for weeks; consequently, they lost the championship game.

• The team practiced for weeks; however, they lost the championship game.

• Because the team practiced for weeks, they lost the championship game.

• The team practiced for weeks, and they lost the championship game.

Answer explanation

The relationship between the two ideas is one of contrast. The conjunctive adverb 'however' correctly expresses this contrast. 'Consequently' and 'Because' incorrectly imply a logical result.

Combine the two ideas by turning the first sentence into a participial phrase.

Complete the new sentence: _____ about the trip, the boy packed his bags a week early.

• He was excited

• Was excited

• To be excited

• Excited

Answer explanation

The past participial phrase 'Excited about the trip' correctly modifies 'the boy' and reduces the clause 'He was excited' into a concise introductory phrase. The other options create sentence fragments or incorrect structures.

Which revision corrects the error in parallel structure in this sentence?

'For my summer job, I am responsible for taking orders, clearing tables, and to wash the dishes.'

• For my summer job, I am responsible for taking orders, clearing tables, and washing the dishes.

• For my summer job, I am responsible for taking orders, to clear tables, and to wash the dishes.

• For my summer job, my responsibilities are taking orders, clearing tables, and to wash the dishes.

• For my summer job, I am responsible for taking orders, I clear tables, and I wash the dishes.

Answer explanation

To maintain parallel structure, all items in a list should have the same grammatical form. This answer correctly uses the gerund form ('-ing') for all three duties, matching 'taking' and 'clearing' with 'washing.'

Combine these sentences using a nonessential relative clause. Complete the new sentence: My bike, _____, is in the garage.

• which has a flat tire

• that has a flat tire

• it has a flat tire

• has a flat tire

Answer explanation

The pronoun 'which' is used to introduce a nonessential clause that adds extra information, and this clause must be set off by commas. 'That' is generally used for essential clauses that do not use commas.

What is the most effective and concise way to combine all three of these sentences?

The dog saw the squirrel. The dog was lying on the porch. The dog suddenly bolted across the yard.

• The dog was lying on the porch and it saw the squirrel, so the dog suddenly bolted across the yard.

• Lying on the porch, the dog saw the squirrel and suddenly bolted across the yard.

• The dog saw the squirrel, the dog was lying on the porch, and it suddenly bolted across the yard.

• After the dog that was lying on the porch saw the squirrel, it suddenly bolted across the yard.

Answer explanation

This option is the most effective because it uses a participial phrase ('Lying on the porch') and a compound predicate ('saw... and bolted') to combine all three ideas smoothly and without repetition.
