Name: <name>Student Number: <student_number>(a) An agent that senses only partial information about the state cannot beperfectly rational.This statement is False.Reason:The agent that sense partial information can be rational agent. Let’s takethe example of street Cameras installed for surveillances. As expected mountedstreet camera can capture the all the images. So, it is rational agent. Here, theperformance measure of the agent is the quality of the images captured. It doesnot sense other information like smell. So, with the partial information, Camera isreasonable and sensible to make the good sense of judgement based on thepartial information. Hence it is proved, it is not necessary for perfectly rationalagent to sense complete information.Let’s take another example of time bucket. Sometime the performance ismeasure for particular time span says for first T times. So, the agent can neglecteverything after T time. Here agent is rational, but it is not sensing completeinformation. The performance is measured for the particular time span, not forcomplete time. Example, we can set the street signals that only works for thepeak time traffic.(b) There exist task environments in which no pure reflex agent can behaverationally.This statement is True.Reason:First of all, we should consider two important percepts – current perceptand previous percept. The decision can be taken based on either of two perceptsor using both.Here, Pure agent is an agent which make the decision or react or take the actionbased on the current percept.
