• What do you already know about the advantages of group living? What other information is related to the question?
o Everything is a trade-off. Group living has advantages and disadvantages. You need to look at each choice and determine if it represents an advantage or a disadvantage. Disease spreads much quicker in large groups of individuals and large groups of individuals will need more food and other resources.
Choose Answer
• Given what you now know, what information is most likely to produce the correct answer?
o More efficient predation, more protection from predators, and the construction of large scale structures are certainly advantages.

Tetanus is a bacterial infection that is commonly acquired from puncture wounds. Why do you need to be vaccinated against the flu every year, but you only need a virus booster against tetanus every 10 years?
A. Antibody production against viruses drops off about 10 times faster than antibody production against bacterial infections, so you need to be vaccinated 10 times more frequently against the flu. B. The flu is everywhere but bacterial infections are incredibly rare, so you don't need to be as careful in maintaining your immunity against them. C. There is a higher rate of mutation in viruses than in bacteria, so you need to change the antibodies you are producing (through vaccination) every year for the flu. D. Infections that enter the body through the bloodstream (like tetanus) are much less toxic than infections that enter the body through binding to epithelial cells (like the flu).
