Answer:
def getChar():
while True:
in1 = input('Enter first char: ')
try:
if len(in1) != 1:
raise
else:
in2 = input('Enter second char: ')
if len(in2) != 1:
raise
else:
break
except:
print('Enter just one character')
return in1, in2
def chars2string(in1,in2):
print(in1*5 + in2*5)
def main():
ls = getChar()
in1 = ls[0]
in2 = ls[1]
chars2string(in1, in2)
if __name__ == '__main__':
main()
Explanation:
The programming language used is python 3.
The script first defines a function getChar and makes use of a while loop in combination with try and except blocks and IF statements, the code ensures that both inputs that are entered by the user after the prompt are 1 in length. i.e. Just one character. This function returns the two characters that were entered.
The second function that is defined is chars2string this function takes two arguments, It repeats each argument five times and returns a joined string.
Finally, the main function is defined and it calls the getChar function first, the values that are returned by this function is assigned to two variables, that is then passed on to the chars2string function. The main function is called and the Joined string is printed to the screen.

Answer:
a) the Statement is Invalid
b) the Statement is Invalid
Explanation:
a)
lets Consider, s: student of my class
A(x): Getting an A
Let b: john
I have a student in my class who is getting ab A: Зs, A(s)
John need not be the student i.e b ≠ s could be true
Hence ¬A(b) could be true and the given statement is invalid
b)
Lets Consider G: girl scout
C: selling 50 boxes of cookies
P: getting prize
s: Suzy
Now every girl scout who sells at least 50 boxes of cookies will get a prize: ∀x ∈ G, C(x) -> P(x)
Suzy, a girl scout, got a prize: s ∈ G, P(s)
since P(s) is true, C(s) need not be true
Main Reason: false → true is also true
Therefore the Statement is Invalid

Answer:
The answer is "Broadband Over Power Line".
Explanation:
The technology that offers and alternative to DSL and high-speed cable is broadband connection which is a term used for high speed internet access using coaxial or fiber optic cables to reach higher speeds than the other technologies. The technology described in the question is "Broadband Over Power Line" which as the name suggests, makes providing broadband internet connection possible using the power lines in the area.
I hope this answer helps.
