Ben Velzian’s experience indicates that ______.

参考解析：

细节理解题。根据文章第二段中的“Recent graduate Ben Velzian was swiping through profits on Tinder and was asked out on a date. While trying to decide where they should meet. Velzian sent his prospective date a PowerPoint presentation full of options of things to do. “I didn’t give him say warming or anything which is perhaps why he didn’t take it in the way I’d expected ... he didn’t say anything, he just blocked me.” Velzian says. So there’s no denying it’s an addictive, powerful tool, but is it past its sell-by-date, as some critics suggest?”可知，Velzian给这个潜在约会对象发送了一个PPT演示文稿，里面包含着约会可做的事情。Velzian说“我没有跟他热情打招呼或是别的，也许这就是他没有给出我预期的反应的原因吧。他什么都没说，直接把我拉黑了。”毫无疑问PPT很强大，让人欲罢不能，但是不是像一些评论家所说的，已经过时了。故选B。
