Respuesta :
A- The crèche and menorah are both religious symbols.
C- The displays were on government property
D- The government does not have the right to endorse or promote religious practices.
The displays were unconstitutional because they violated the First Amendment, which prohibits the government from adopting explicitly favorable behaviors regarding a specific religion. The reason for this unconstitutionality were that the creche and menorah are religious signs displayed on government property, and government does not have the right to promote religious practices (due to the mentioned First Amendmend to the U.S. Constitution).
