A couple adopts two teenagers who were raised in other cultures. One teen's original culture values collectivism, while the other's values individualism. One day the couple wakes up to find that someone has caused a big dent in the family car. Given research on group cooperation, how should they interrogate the teens to get them to confess about who is responsible?

	a.	Offer each teen the same options, knowing that defection is likely because of their different background cultures.
	b.	Emphasize to the collectivist teen that defection is actually better for the two siblings in the long-term.
	c.	Ignore the collectivist teen, who is more likely to cooperate.
	d.	Offer each teen the same options, knowing that defection is likely because they are a newly formed group.
