Answer:
a. True
Step-by-step explanation:
It is true that in-person meetings arranged by people over social networking sites are called meetups. This is a reference to the fact that people are able to "meet up" in these gatherings. Social networking sites are a great way to expand our social circle and meet people that we might not otherwise be able to meet. This can bring many benefits to our personal, as well our professional life. However, it is always a good idea to exercise caution when meeting up with strangers.
