check all that apply

1. is less important than an experimental group.
2. can be compared with an experimental group to assess whether one particular variable is causing a change in the experimental group.

2 & 4

Not 1 because without a control the results would not be considered valid

Not 3 because you can conduct experiments in places other than in a laboratory.  To take an extreme example, robotic Mars explorers conduct experiments to see if there is life on Mars - the nearest lab is millions of miles away from them
