As part of legislation enacted for the stated purpose of improving science skills of schoolchildren, congress appropriated funds to permit public school teachers who had been certified by state school districts as science lab instructors to provide supplemental science instruction to any students in either public or private schools who did not have access to science lab resources. to ensure content neutrality, the statute required the instructors coming to the private schools to use portable science labs supplied by the public school districts, which contained the equipment and experiments that the instructors used for the same purpose in the public schools. a citizens' group filed suit in federal district court to challenge the constitutionality of funding the science teachers for private schools, alleging that most of the private schools covered by the statute were religiously affiliated schools. no members of the group have any children in either public schools or private schools affected by the statute. how is the court likely to rule? a dismiss the case on the pleadings, because the citizens' group does not have a sufficient stake in the controversy to have standing to challenge congress's expenditure, which was authorized under its power to spend for the general welfare. b decide the case on the merits in favor of the government, because the legislation defines the context in which instruction can be provided in private schools so as to avoid excessive government entanglement with religion. c decide the case on the merits in favor of the citizens' group, because the appropriation's primary effect advances religion in violation of the establishment clause of the first amendment. d decide the case on the merits in favor of the citizens' group, because the court will presume that any instruction provided on the premises of a religiously affiliated school will be influenced by religion.
