NEED HELP PLEASE its summertime, and some friends are setting up for an outdoor picnic in the park. As they're working, they feel the wind getting stronger and the temperature dropping. They hear from a radio report that the air pressure is dropping, too. What should they do next?

A. put up more umbrellas to protect against sun burns.

B. put everything away to avoid the coming snowstorm

C. move the picnic into a shelter. because rain is on the way

D. Ask the park manager to turn on lights for the coming fog.

That is no problems. if you answer my questions, i will give you brainliest answer, so go check that out.

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
