I have just installed latest version of ubuntu on my laptop Dell Vostro 3350 and my Wi-Fi works just fine, but the Bluetooth is not working or detected at all.

Below a screenshot from my laptop:

Please be specific; latest means what? Ubuntu 21.04 Desktop? (or the 2021-April release of desktop)

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.
