A schооl thаt dоes not hаve аir conditioning has published a policy to close school when the outside temperature reaches or exceeds . The following code segment is intended to print a message indicating whether or not the school is open, based on the temperature. Assume that the variable degrees has been properly declared and initialized with the outside temperature. if (degrees > 95) System.out.println("School will be closed due to extreme heat");else System.out.println("School is open"); Which of the following initializations for degrees, if any, will demonstrate that the code segment may not work as intended?
