	c) The covered pot shows a greater temperature increase than the uncovered one.		d) Both pots show a decrease in temperature.

Q.2	Consider the following scenario and choose the correct option. Scenario: You're a college student living in a shared hostel room with two other roommates. You've noticed increased common illnesses among your roommates, like colds, flu, and stomach upsets. You suspect poor hygiene might be playing a role. Instructions: Choose the MOST LIKELY way your hygiene habits could contribute to your roommates' health problems, and explain your reasoning.
	a) You always shower after gym class, but you only wash your hands before eating.		b) You keep your laundry hamper overflowing with dirty clothes for days before washing them.
