it's a strong base but you must be more specific

I have another orgo question for you...

I have an older version of topscore and came across a question that asked for the product of BrH2C-CH2Br with KOH. From what I was told in my orgo class this reaction can only form an alkene via dehyrdohalogenation...but topscore says the answer is an alkyne. I thought that in order to form an alkyne a stronger base than KOH was required (Like something with NH2). Am I wrong or is this a topscore mistake?

Thx

Topscore is right.

That's a comforting thought...my professor told our class that KOH couldn't be used for this type of reaction...

Hopefully, this was his only mistake. If not, I'm going to be in trouble with the OC section.
