The sensors needed to make a smartphone effective can put users’ information at risk. What are the costs and benefits of the sensors that allow smartphones to collect information? How would our smartphones be altered if these sensors were disabled or less effective? Is this would be worth the protection of an individual’s privacy?

 D. The employees where Marcy works have had no training in fire safety procedures.  i would say this is the right answer because by reading the given evidence, we can conclude that the employees are confused as to what is going on. they don't know what to do or whether it was a drill or not. they didn't take necessary safety procedures because they weren't informed of them or trained in the case of fire safety.
