Small, prolific mussels called zebra mussels were first introduced into the great lakes by a foreign cargo ship. they became a serious problem because they attached themselves to smooth, hard surfaces, and often clogged water intake pipes. congress determined that zebra mussels posed a great threat to the economic welfare of the great lakes region and passed a statute requiring all great lakes water intakes to be coated with a special chemical compound that repels zebra mussels. studies by biologists at a major state university showed that while the special chemical compound that the federal government has required was effective, it also was toxic to other aquatic life. the biologists recommended that great lakes intake pipes be coated with a less toxic and less expensive copper-based paint. on the basis of those studies and the recommendation, three great lakes states adopted laws permitting municipal water districts to coat their intake pipes with copper paint. can municipalities using copper-based paint on their intake pipes successfully be prosecuted for violating the federal law? a no, because the tenth amendment prevents congress from interfering with integral government functions. b no, because the municipalities are taking effective steps to combat zebra mussels in compliance with the spirit and purpose of the federal law. c yes, because congress is in a better position to regulate the entire great lakes region than the individual states. d yes, because congress may adopt laws regulating navigable waters.

An employee of the state government always received his state paycheck on the last workday of the month. the employee was not a good money manager, and just barely managed to make it from paycheck to paycheck each month. on the second to the last workday of the month, the employee had $45 in his checking account, and, needing to buy a birthday gift for his sister, he wrote a check to a gift boutique for $100. he knew that he would be receiving his paycheck the next day, so he could deposit the paycheck before the check would be sent to the bank.however, unbeknownst to the employee, the state legislature was having a budget impasse. because the state constitution prohibited any deficit spending, state employees were not paid as usual. without a paycheck to deposit, the check written to the gift boutique was returned for insufficient funds. the merchant complained to the police, who arrested the employee and charged him under a statute that prohibited "issuing a check knowing that it is drawn against insufficient funds, with intent to defraud the payee of the check."what should be the outcome of the employee's prosecution? a not guilty, because the employee intended to deposit his paycheck the next day.b not guilty, because it was reasonable for the employee to expect that he would receive his paycheck as usual.c guilty, because the employee knew when he wrote the check that he did not have sufficient funds in his account to honor it.d guilty, because reliance on a future source of income does not vitiate the employee's violation of the statute when he wrote the check.
