Hello. You have not entered the text to which this question refers, which makes it impossible for it to be answered. However, when searching for that question I was able to find another question exactly the same as the article "How Video Games Are Getting Inside Your Head" as the text in question. If this is your case, I hope the answer below can help you.
Answer:
C. Game companies research ways to influence gamers, encouraging them to play longer and to spend more.
Explanation:
The text shows how the gaming industry has a great capacity to attract customers. This capacity is intensified with a strong study in the target public of these industries, where it is possible to recognize the preferences of the customers and intensify those preferences in the next games that will be launched causing the customers to buy more games and spend more time playing. The text presents this statement as the central idea of the entire text, which is the subject on which all arguments are established.
IDK what you're asking, but I'm guessing it's the grammar...
So the sentence you put in the question is:
<span>Mona. arrived on time, but. there was traffic.
</span>↑ <span>↑</span>

All days are not special. But few days stand in our memories and make us feel nostalgic. One such day is my successful project in history. I collected 100 coins of 10 different countries and kept it as an exhibit in my school. There was no end for the appreciation I got from all teachers. My friends were so astonished at my collections. I shared a lot of information and it gained a good name of me in my school. That day was the most proud filled and memorable day in my life.
