Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year — they are often green and striped, or have plenty of bumps and bruises — heirlooms are more flavorful and thus in increasing demand.

The sentence starts with a contrasting word (Although) followed by a verb-ing modifier (appearing). So, we expect to read something that appears less appetizing, and we also expect to read some information contrasting to this fact. As we read the sentence, we come across “heirloom tomatoes”. The verb-ing modifier makes perfect sense with heirloom tomatoes. These tomatoes can appear less appetizing than most of their round and red supermarket cousins.
Then, we have a verb-ed modifier “grown…”. This modifier provides additional information about “heirloom tomatoes”. These tomatoes are grown from seeds saved during the previous year. Everything seems fine till now!
The sentence then presents some information between two em-dashes. This means that it is additional information, and the sentence will make sense even without this information. It doesn’t mean that you shouldn’t read this information; what you should do is that once you have read it, assume it is not there for evaluating the grammar and structure of the main sentence. This part says that heirlooms are often green and striped, or have plenty of bumps and bruises.
As we read further, we read “heirlooms are more flavorful”. Oh wait! We were still waiting for the verb for “heirloom tomatoes”. Right? And now, we have another clause starting. There is no verb for “heirloom tomatoes”. A major error!
As we read, we see that this part says that heirlooms are more flavorful and thus in increasing demand. As we try to connect it with the sentence read so far, we realize that this information is the second part of the contrast. The sentence essentially wants to present the following contrast:
- Although heirlooms appear less appetizing, they are more flavorful and thus in increasing demand.
Therefore, the original sentence has one error.
(Some people carry a misconception that ‘Although’ need always be followed by a clause and cannot be followed by a modifier. I have written an article that clears this misconception. Click here to read the article.)
(A) Incorrect. For the error described above.
(B) Correct. In this option, the action of appearing has been changed from “verb-ing” modifier to a verb. Therefore, we have a verb for “heirloom tomatoes” now. So, the only error in the original sentence has been corrected. Also, the contrast in this option is what we figured in the sentence analysis.
(C) Incorrect. No verb for “heirloom tomatoes”.
(D) Incorrect. In the absence of “Although”, the first part of the sentence becomes an independent clause, which is not joined properly with the second independent clause. Also, this option distorts the intended meaning of the original sentence by eliminating the contrast.
(E) Incorrect. No verb for “Heirloom tomatoes”.
