Time for some teasers...

Let's start with this one meant for young kids, which I found in today's Sunday Times:

All you need to do is to match each bird to its nest site. Easy-peasy, right? After all, it is meant for kids. But I got two wrong answers. The answers (inverted above, and in smaller print) may not be easy to see, so I'll type them out, but after the next teaser!...

Next, I remembered this riddle from a long time ago...

What occurs once in a minute, twice in a moment, but never in a thousand years?

(I'll give the answer after I pose the last riddle, below.)

-----------------------------------------------------

I came across this interesting logic riddle:

You arrive at this portal with nothing but two doors, each with a man standing guard. One door leads to Heaven and the other leads to Hell. One guard always tells the truth; the other always lies. You have to pick one door to go through, and you can only ask ONE question ie, you must decide which guard to approach, and you do not know who is the truth-teller and who is the lier. How do you make sure you get to Heaven?

--------------------------------------------------------

Don't be too quick to give up and get the answer below. Think about it first. Meanwhile , here's the answer to the previous riddle:

The letter "m".


Ok, here's the last riddle's answer:

Go to either guard and ask this double-barrel question: "Is the truth-telling person standing at the door to Heaven?" Because of the way the question is framed, and because each guard must respond according to his "script", the answer will be the truth, be it a "yes" or a "no"!
