Answer:
The 3 correct answers are: B: Had larger brains than their predecessors, C: used complex language, and F: cooperated in hunting and in building shelter.
Explanation:
In the "Homo sapiens" name, the word "sapiens" makes reference to "wise man", because they evolved with a bigger brain than their predecessors, which made them able to develop a complex language, so they can communicate better.
Also the Homo Sapiens skin went through various weather adaptations because of their constant migration, so the way they covered themselves against cold was using animal skin to create shelters.
