Is 'beleive to be' an idiom.. Any how I opted out A based on this
one - an explosion are in sync

an explosion that is believed to be a type unknown or a type of explosion that is belevied to be unknown to science
First take: 640 (50M, 27V) - RC needs 300% improvement
Second take: coming soon..

Hi AIM
I interpreted type == kind
But I was expecting a kind of or a type of explosion that is unknown...


SO what is the OA rohu
First take: 640 (50M, 27V) - RC needs 300% improvement
Second take: coming soon..

Logically, a supernova is not a type: it is an explosion OF a type. C is the only possible option.
