Which of the following regarding looking up words in a dictionary is true

Are your options these?
A. Print dictionaries generally contain audio attachments.
B. If a word has two definitions listed, you need only pay attention to the first one.
C. If a word has two pronunciations listed, the first one is considered the more common.
D. Print dictionaries rarely offer synonyms, whereas online dictionaries do.

If that is the case, the correct answer is C. If a word has two pronunciations listed, the first one is considered the more common. 
A is correct, but it has nothing to do with looking words up. B is incorrect because both definitions are equally important. D is incorrect because both versions offer synonyms.

Just go to edit profile adn then to preferences and find the option to change it and bam you got it.

The factors might be:
peer pressure
wanting to try new things
bad influences in group of friends
famous people doing things
social media showing wrong ideas
