Successful as they were on rivers and lakes, steamboats were never able to cross the atlantic.
a. true
b. false

True. Steamboats were not able to cross and trudge the biggest body of water on Earth because they are mostly powered by coals. Coals that deplete easily and need re-supplying are the number one hindrance of steamboat engines that is why they were only used for river cruising or travel because they may stop in between locations where they can re-supply. 

May consider a group  g=({0,1},+)g=({0,1},+)where  ++  will work as the xor operator like we work in boolean algebra. note here, that ‘00’ and ‘11’ are not the usual 0 and 1 that we work with everyday. the elements are  called  ‘00’ and ‘11’ and  may not mean  zero (nothing) and one (single). ‘00’ is the identity for the given binary operator +, meaning that any element operated with ‘00’ gets us that element itself.  for a set  ss  in  g′g′  having more elements than just  {0,1}{0,1}  the values for  a+b∈sa+b∈s, such that  a∈s,b∈sa∈s,b∈s, have to be first defined, only then can you determine the value of  1+11+1. the answer could possibly have been  22  if oanswer is25,000

Iwould choose c or d
