In a famous series of experiments conducted by Harry Harlow, infant monkeys were separated from their mothers at birth. The infants were then given two surrogate mothers (a terry-cloth "mother" and a wire "mother"), each of which alternately had a nursing bottle that provided food to the infants. The experimental results showed that in frightening situations the infant monkeys:.
a) were more likely to become aggressive toward the wire mother than toward the terry-cloth mother
b) preferred the wire mother, even when the terry-cloth mother had the nursing bottle
c) preferred the terry-cloth mother, even when the wire mother had the nursing bottle
d) would run and cling to whichever mother had the nursing bottle

C). Preferred the terry cloth mother even when the wired mother had the nursing bottle.

Explanation:

As per the given description, the experimental results displayed in the experiment conducted by Harry Harlow is that the infant monkeys in terrifying situations 'preferred the terry-cloth mother even when the wired mother had the nursing bottle'. Harlow's experiment aimed to show the preference of love and affection on human behavior over the hard wire which served mere as a food-provider to the child. Thus, the child preferred spending time with the soft cloth that gave motherly and comforting feel to the infant instead of the hard wire to which the child clung just for food. Therefore, option C is the correct answer.

the correct answer is modern american cars are not available due to trade restrictions.

trade between cuba and the united states have serious restrictions. the u.s. imposed an economic embargo on cuba, that among other things means that modern american cars are not available due to trade restrictions.

in response to some governmental actions of the authorities from cuba, president john f. kennedy proclaimed an embargo on trade between both countries in february 1962. the trade embargo remains active until this day and was implemented directly by the departments of commerce and the department of treasury.

in president trump’s administration, there is a national security presidential memorandum that "strengthens the policy of the u. s.", affecting trade with cuba.
