A)scarcity and shortages are really the same thing.
this is the answer
Calvin's professor can conclude that Calvin has been an observational kid.
Explanation:
The observation Calvin makes is a rather arbitrary one but one that can invite broader concern nonetheless.
Some kids start bobbing their heads and raising them before they can ever turn while the other develop these skills in the opposite order.
It would remain to be seen if Calvin would think something can be inferred from this otherwise rather standalone observation of things or not as there may be a study on how far this can be taken in child psychology.
At any rate, he is an observational student and the professor can put that to use.
Answer:
B). Danny.
Explanation:
As per the given description, Danny has the most probable chances of success as his therapist uses hypnosis(extremely focused concentration) that would help him to remain relaxed during the time of dental surgery as his entire concentration or focus would be devoted to a specific thing. Thus, he would not be able to experience pain while undergoing surgery and feel relaxed. Therefore, Danny has the most probable chances of being successful as the others are either using the method inappropriately or for an inappropriate cause('recall the night he was supposedly abducted by aliens'). Hence, <u>option B</u> is the correct answer.
D. Mountains and Basins.
Hope this helps!
