Carefully evaluate each of the following items and provide a response using the provided answer sheet.Each question is worth $4$ points. Clarification is avallable, but subject to instructor discretion$\mathrm{.}1)$The working definition of strong Al holds that a truly intelligent systema.should follow the same methods of learning and cognition as humans, and should be as general$-$purpose as human intelligenceb. may use reasoning processes different from humans as long as it can explain its decisions may use reasoning processes different from humans if it reaches the same conclusions should follow the same methods of learning and cognition as humans, but may be limitedd$.$ to specific application domains e$.$None of these are correct$\mathrm{.}2)$Why is A search the most commonly used heuristic search technique?a$.$It is not encumbered by a patent or other use restrictionsb. It was developed early in computing history and has been standard practice ever sincec$.$ It's not only optimal, it's optimally efficientd. it is particularly easy to implemente. It only needs a small amount of memorySuppose we're using constraint satisfaction and have satisfied all constraints. We aresearching the remaining state space. We have several variables we could choose to as values to next. What's a common heuristic for selecting the next variable?a$.$ Choose any convenient variable, since choice order doesn't matterb. Choose the variable which requires the fewest unrealistic assumptionsc. Choose the variable with the median number of constraints related to other variabd. Choose the variable with the most constraints $($highest degree$)$ relating to other v$.$e$.$ None of these are correct.
