Answer:
b. False
Explanation:
False, unchecked exceptions do not cause compilation errors and do not require try/catch blocks or throws statements. However, although they are not required it is good programming to include them in order to handle any exceptions that may arise. If you do not include a proper way to handle such an exception the program will still run but may run into an exception during runtime. If this occurs then the entire program will crash because it does not know how to handle the exception since you did not provide instructions for such a scenario.
Answer:
Explanation:
The population in western richer countries is decreasing but the population in some poorer developing countries is increasing and normally in the poorer communities where education is minimal or not encouraged then men and women tend to get married young and have many children. Population management is not necessary because when men and women are educated and have good standard of living with a good social system of caring for the old then married couples will tend to have one or two kids or none at all. Population control was practised by PrC and it managed to alleviate 60% of the people out if poverty and reduced the population by implementing one child policy. Now China has more male than female creating social problems of finding a wife. In the West with good social system to care for the elderly more couples are not having children. In the west where living conditions and educational level are better the Caucasian race is not having that many children as the other races in developing countries. Education and financial independence of women will encourage married women to have one or two kids so that they can still pursue their career after marriage. With modern contraception you can delay having children until you are ready for them. The concept of delaying marriage to reduce population does not hold true. However the whites’ population is decreasing every year as compared to the other non white races. The reason is that in the poorer non white countries the population is higher because of subservient position of the women who have no say in birth control

Answer:
Required code is given below:
Explanation:
def add_to_dict(dictt, key,value):
if key in dictt.keys():
print("Error. Key already exists.")
else:
dictt[key]=value
return dictt
def remove_from_dict(dictt,key):
try:
dictt[key]
dictt.pop(key, None)
return dictt
except KeyError:
print("No such key exists in the dictionary.")
def find_key(dictt,key):
try:
value=dictt[key]
print("Value: ", value)
except KeyError:
print("Key not found.")
