<p>Unfortunately, one of those species is the (Bark scorpion, just about the only species) whose venom is considered truly dangerous and often fatal to humans
A. No change
b. Bark Scorpion which is just about the only species</p>
<p>the answer is a. But don't you need to insert a comma before "which" to make this sentence correct?<br>
Please help me out, thank you so much!</p>
<p>Not sure what the question is. Are you saying that answer choice “b” needs a comma? </p>
<p>@An0maly yeah, that’s what I meant. And the answer is B. I guess I was somewhat unconscious when typing things on tablet…</p>
<p>So B is the correct answer?</p>
<p>I had to look this up because I also was confused. Found this online:</p>
<p>You do not need to use a comma when “which” is used to start a restrictive clause. A restrictive clause gives information that is necessary for understanding:</p>
<p>ex: The box of apples which is by the door can be used to make the pie.</p>
<p>In this instance, the clause restricts (limits) the subject. We can’t use the box of apples on the table or the one outside. We can use the one by the door. </p>
<p>When “which” is before a non-restrictive clause you do need a comma. A non-restrictive clause adds information that is not necessary. </p>
<p>ex: That box of apples, which I picked this morning, can be used to make the pie. </p>
<p>Edit:
In your scorpion example:</p>
<p>Unfortunately, one of those species is the Bark scorpion which is just about the only species whose venom is considered truly dangerous and often fatal to humans</p>
<p>vs </p>
<p>Unfortunately, one of those species is the Bark scorpion, which just about the only species, whose venom is considered truly dangerous and often fatal to humans.</p>
<p>The first one makes more sense because in the second one if you put a comma before which you would need another comma after “species.” And that doesn’t make any grammatical sense. </p>
<p>I had no idea this rule existed (I’m not a grammar wiz haha). My explanation could be completely wrong. </p>
<p>@WasatchWriter yeah, B is the correct answer. I am sorry, I made an error last night…</p>
<p>@K1Helen Thanks a lot!</p>
