Hi, carechimba. Keep on is a little more insistent than keep, but both are correct and very common. You should start a separate thread for separate questions, but I would change your sentence like this: What a wonderful apology for a medicine as great as Cannabis, or for such a great medicine as Cannabis. The is sounds awkward to me.
Fortunately, already in May, 2016, CBS has picked up âCode Blackâ for a second installment. On June 21, 2016, CBS has published its premiere schedule for this fall. According to the schedule âCode Blackâ is returning for Season 2 on Wednesday, September 28, 2016, on CBS.
Season 4 of Orphan Black is set to premiere in April 14th, 2016 on BBC America at 10/9c and aired its season finale on June 16, 2016. It had 10 episodes like seasons prior. However, unlike past seasons, rather than air on Saturdays, it aired on a new night on Thursdays at 10/9c.
