Contrast Clauses: Although, However, and Though: correct answers
Jump to answers ↓How These Words Work
Although, though, and however all express contrast — they tell the reader that two ideas don't fit together the way you'd expect. The tricky part is that they don't all work the same way grammatically, and mixing up their punctuation or position is one of the most common mistakes at this level.
Although and though are conjunctions. They connect two clauses inside the same sentence. However is a linking adverb. It connects two separate sentences (or two independent clauses joined by a semicolon). This single difference controls almost everything about punctuation and word order.
Although and Though — Inside One Sentence
Use although or though to introduce a contrast clause that attaches to a main clause. The contrast clause can come first or second:
✅ Although the restaurant was expensive, the food was disappointing. ✅ The food was disappointing although the restaurant was expensive.
When the although/though clause comes first, put a comma after it. When it comes second, a comma is usually optional (many writers skip it).
Though is slightly less formal than although, but in most writing and speaking they're interchangeable. One difference: though can go at the end of a sentence as an afterthought, almost like "but." Although cannot.
✅ The hotel was noisy. The beds were comfortable, though. ❌ The hotel was noisy. The beds were comfortable, although.
However — Between Two Sentences
However does not glue two clauses together the way although does. It comments on the relationship between two independent statements. That means it needs a full stop or semicolon before it, and a comma after it:
✅ The exam was difficult. However, most students passed. ✅ The exam was difficult; however, most students passed.
Compare with the conjunction version:
✅ Although the exam was difficult, most students passed.
All three sentences above mean roughly the same thing — but the grammar is different.
The Mistake Almost Everyone Makes
The single most frequent error is using however as if it were although — sticking it between two clauses with just a comma:
❌ The weather was terrible, however we decided to go hiking.
This creates a comma splice (two full sentences glued with only a comma). Fix it in one of three ways:
- Replace the comma with a full stop: The weather was terrible. However, we decided to go hiking.
- Replace the comma with a semicolon: The weather was terrible; however, we decided to go hiking.
- Switch to a conjunction: Although the weather was terrible, we decided to go hiking.
Another common slip is doubling the contrast — using although and but in the same sentence, which cancels itself out:
❌ Although she studied hard, but she failed the test. ✅ Although she studied hard, she failed the test. ✅ She studied hard, but she failed the test.
Pick one or the other. Although already does the job of but; you don't need both.
Position Flexibility
However can move around within its own sentence. Wherever it lands, set it off with commas:
✅ The train was late. The passengers, however, remained calm. ✅ The train was late. The passengers remained calm, however.
Although and though stay at the front of their own clause — they can't float to the middle the way however can. (Remember the one exception: though alone can sit at the end of a sentence as an informal afterthought.)
A quick mental test: if you can replace the word with but and keep one sentence, use although/though. If you need two sentences, use however.
Correct answers
Question 1
Complete the roommate's defense of their terrible furniture choice.
"I admit that the neon green velvet sofa is a crime against interior design. It is incredibly comfortable, _____."
The correct answer is though.
In conversational English, though can be used as an adverb at the very end of a sentence to mean "however." Although and even though are strictly conjunctions and must appear at the beginning of the clause they introduce; they cannot be placed at the end of a sentence.
Question 2
Complete the detective's incident report about a very clumsy burglar by choosing the correct word for each gap.
The suspect successfully bypassed the high-tech laser grid, although he immediately tripped over the family's sleeping poodle.
He was wearing a state-of-the-art stealth suit. The bright neon pink color, however, made him incredibly easy to spot on the security cameras.
He had brought a massive duffel bag for the diamonds. He escaped with nothing but a half-eaten sandwich, though.
The suspect successfully bypassed the high-tech laser grid, although he immediately tripped over the family's sleeping poodle.
"Although" joins two clauses in the same sentence. "However" would require a semicolon or a new sentence here.
He was wearing a state-of-the-art stealth suit. The bright neon pink color, however, made him incredibly easy to spot on the security cameras.
"However" can interrupt an independent clause to provide contrast. It is set off by commas. "Although" cannot be used as an interrupting adverb in this way.
He had brought a massive duffel bag for the diamonds. He escaped with nothing but a half-eaten sandwich, though.
"Though" acts as an adverb meaning "nevertheless" when placed at the end of a sentence. "Although" and "despite" cannot go at the end of a sentence.
Question 3
Help the food critic complete her savage restaurant review.
The chef's signature dish was beautifully presented; _____, it tasted like salted cardboard.
The correct answer is however.
However acts as a conjunctive adverb here, connecting two independent clauses. It typically follows a semicolon and is followed by a comma. Although and though are subordinating conjunctions and cannot be used with this semicolon-comma punctuation pattern. Despite is a preposition and must be followed by a noun phrase, not a full clause.
Question 4
Help the food critic finish her scathing review of a confusingly named restaurant by choosing the correct contrast word for each blank.
The chef claims the dish is a masterpiece. I found it tasted exactly like soggy cardboard, though.
The flaming dessert was visually stunning; however, it exploded when I touched it with my spoon.
I will probably eat there again next week although the prices are completely astronomical.
The chef claims the dish is a masterpiece. I found it tasted exactly like soggy cardboard, though.
When placed at the very end of a sentence, we use the adverb "though" to show contrast with the previous sentence. "Although" cannot be used at the end of a sentence.
The flaming dessert was visually stunning; however, it exploded when I touched it with my spoon.
"However" is a conjunctive adverb that connects two independent clauses. It is typically preceded by a semicolon (or a period) and followed by a comma.
I will probably eat there again next week although the prices are completely astronomical.
"Although" is a subordinating conjunction that introduces a dependent clause (subject + verb). "Despite" is incorrect here because it must be followed by a noun phrase or gerund, not a full clause.
Question 5
The correct answers are:
- Although the dessert looked like a burnt tire, it tasted absolutely divine.
- The dessert looked like a burnt tire; however, it tasted absolutely divine.
Although is a subordinating conjunction. It connects a dependent clause to an independent clause (e.g., Although [subject] [verb], [subject] [verb]). We do not put a comma immediately after "although."
However is a conjunctive adverb. When it connects two independent clauses, it requires a semicolon before it and a comma after it. It cannot be used exactly like "although" at the start of a dependent clause.
Question 6
Even though we had packed plenty of industrial-strength bug spray... ...survived the first night; however, I am seriously reconsidering... ...definitely not touching it, though, because it looks...
Even though is a stronger version of "although" and is followed by a full clause (subject + verb). "Despite" is incorrect here because it must be followed by a noun phrase, not a clause.
However is the correct transition between two independent clauses separated by a semicolon.
Though can be tucked at the end of a clause (right before the comma and the "because" clause) to add a conversational note of contrast.
Question 7
Read the student's desperate email to their professor. Choose the appropriate contrast and transition word for each blank to complete the message.
I completed the entire essay on time; however, my cat walked across the keyboard and permanently deleted the file.
I am asking for a 24-hour extension, although I know your syllabus strictly forbids late work under any circumstances.
I did manage to recover the title page and the bibliography, though.
I completed the entire essay on time; however, my cat walked across the keyboard and permanently deleted the file.
"However" correctly shows contrast and fits the punctuation (semicolon before, comma after). "Therefore" would incorrectly imply the cat deleting the file was the result of finishing the essay.
I am asking for a 24-hour extension, although I know your syllabus strictly forbids late work under any circumstances.
"Although" introduces a dependent clause that contrasts with the main clause. "Because" would incorrectly mean the student is asking for an extension due to the strict rule.
I did manage to recover the title page and the bibliography, though.
Used at the end of a sentence, "though" functions as an adverb showing contrast with the previous negative information. "Although" cannot be placed at the end of a sentence.
Question 8
The correct answers are:
- The alien has eight tentacles. It is quite friendly, though.
- Although the alien has eight tentacles, it is quite friendly.
Though can be used as an adverb at the very end of a sentence to show contrast. "Although" cannot be used this way.
When using although as a conjunction, it introduces a dependent clause and is separated from the main clause by a comma. We never use a semicolon followed by "although."
Finally, using a comma before however to connect two complete sentences creates a "comma splice," which is grammatically incorrect. It needs a period or a semicolon!
Question 9
...not entirely sure how to eat it, though. Although the artistic presentation was flawless... The prices, however, were completely astronomical!
Though can be used as an adverb at the very end of a sentence to mean "however" or "nevertheless." This is very common in spoken and informal English. ("Although" cannot be used this way.)
Although is used at the beginning of the dependent clause to introduce the contrast about the presentation.
However is often used as an interrupting adverb in the middle of a sentence to emphasize a contrast. When used this way, it is framed by commas.
Question 10
Choose the right word to complete the student's highly suspicious excuse.
_____ the aliens promised to return my math homework, I suspect they used it as spaceship fuel.
The correct answer is Although.
Although is a subordinating conjunction used to introduce a dependent clause that contains a subject and a verb ("the aliens promised"). However and nevertheless are conjunctive adverbs and cannot connect a dependent clause to an independent clause in this way. Despite is a preposition and must be followed by a noun or a gerund, not a full clause.
Question 11
Although I appreciate your deep love for tropical climates... ...however, I expect you to actually wear it...
Although is a subordinating conjunction. It connects a dependent clause ("Although I appreciate...") directly to an independent clause ("...setting our apartment... is unacceptable").
However is a conjunctive adverb. It is used to show contrast between two independent clauses, and it is usually preceded by a semicolon (or a period) and followed by a comma. "Despite" is incorrect in the first blank because it must be followed by a noun or gerund, not a full subject-verb clause.
Question 12
The correct answers are:
- I finished the essay on time; however, my dog literally ate my laptop.
- Though I finished the essay on time, my dog literally ate my laptop.
- I finished the essay on time. My dog literally ate my laptop, though.
However is used with a semicolon (or a period) and a comma to link two independent ideas.
Though can act as a subordinating conjunction at the beginning of the clause (just like "although") AND as an adverb at the end of a sentence.
"Although" cannot be followed immediately by a comma to start a new sentence (that creates a sentence fragment), and "however" cannot be squeezed between two commas to join two full sentences (that creates a comma splice).
