I am not able to increase or decrease the brightness level of my device. Even if i change the brightness level from the settings the brightness level doesn't change. I even tried the hot keys. They show the level of brightness chamging but the brightest and the dimmest is the same.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
