                        A badminton coach was trying to put together a team of 4 players for a friendly badminton championship out of 7 players. R, S, T are the male players, and W, X, Y, Z are the female players. Note that all players have equal ability, and the team needs to have atleast 2 male players. While selecting the team we need to keep in mind that all 4 players should be able to play with each other. We also need to keep the following restrictions in mind:
                        

                        - R cannot play with Y
- S cannot play with W
- T cannot play with Z
                        

                        Which of the following are true:

A: S and Z cannot be in the team together.
B: T and Y cannot be in the team together.
C: T and X cannot be in the team together.
                        

                        A code ("EIG AUC REO RAI COG") was sent to the criminal office by a CID agent named Batra.  However, four of the five words are fake, with only one containing the information. They also included a clue in the form of a sentence: "If I tell you any character of the code word, you will be able to tell how many vowels there are in the code word." Are you able to figure out what the code word is?
                        

                        A: RAI

                        Myra is working on her thesis for which she created a scatter plot of the number of teachers and the number of college graduates for cities in Australia. She noticed a positive correlation. Which of these do you think is the probable explanation for this correlation?
                        

                        A: Teachers encourage people to go to college, so an increase in the number of teachers leads to an increase in the number of college graduates. 

B: Some college graduates choose teaching as a profession after graduating, so an increase in the number of college graduates also leads to an increase in the number of teachers.

C: There are more college graduates and teachers in higher income cities, so income is a confounding variable here, make it difficult to prove causation between number of teachers and number of college graduates. 

D: Cities with a higher population have more teachers and more college graduates, so the correlation is due to a third variable (population of city).

E: The provided data is insufficient, so it is extremely difficult to establish the reason for the correlation.

F: Most college students choose non-teaching professions after graduating, which explains the correlation. 

G: In Australia, college students are encouraged by their teachers to choose teaching as a profession after graduating.

                        Alex’s uncle is a magician who gave them a magic bag in which coins get doubled each time you put those coins into it. Initially, Alex had few coins with them. So, Alex put all the coins, and the coins got doubled. Alex took out all the coins and gave a few to their friend and then again put the remaining coins back in the bag.

                        A large real estate company conducted a recent study of their customers. The study was designed to uncover insights regarding the main criteria for choosing to invest in a residential property. A majority of the customers surveyed stated the 'returns profile' was their main priority, followed by 'development potential' and 'stability of income'. 'Portfolio legacy' ranked at the bottom in the list of factors. It was interesting to note that respondents were less likely to have residential holdings that formed part of mixed-use assets i.e. as an add on to commercial investment. One might assume that more investors are proactively investing in residential real estate rather than having incidental exposure via business investments. 
                        

                        Based on the given passage, what can we say about the following statement?

Business owners having commercial premises often have a residential property as part of their portfolio.
