There is a（n） （61）A of the growing digital trend：YouTube shows the teenagers all over the world are watching the same videos and laughing at the same jokes，indicating that they are more （62）B than teenagers in the past．They may be keen on （63）B their friends and posting updates on social media sites，but teenagers today are probably going to have access to technology and （64）Bsocial and educational opportunities that anyone with a less flexible brain may have trouble imagining．Nevertheless，there is a cut-off point，and by the age of 30，our brains in their ways，making it more（65）C for us to adapt and cope with new technologies．
