Finally! [Indeed. Now try it without that word! Harry]
26th June 2020 at 11:03 am #4936710degrees-adminKeymaster[…], because [….].
[Oh, I really like that answer, though it isn’t the one we had in mind! Harry]
29th June 2020 at 4:00 pm #4942610degrees-adminKeymasterPull is the only one without a homophone.
Per post #49365, the next would be Dessert, because its homophone is not a musical term.5th July 2020 at 5:58 pm #4949210degrees-adminKeymaster@Harry, is there something missing in the GCHQ puzzle 15 solution? [I will check, Harry]
16 was pretty easy.
[Position wasn’t important, and you got the right answer. Well done. Harry]5th July 2020 at 6:11 pm #4948910degrees-adminKeymasterEh? Where is Challenge 15’s answer?
[Apologies, set the wrong page to publish. Have fixed it now. Did you work it out? Harry]
5th July 2020 at 11:33 pm #49497InactiveFor Challenge 15 – I may be missing something here… I agree that “NCS from Nicosia, the capital for CyprUs” is a
- possible
answer, but the question asks “What is the
- only
possible way to complete this sequence?” – why wouldn’t, say “TTW from Ottawa, the capital of CAnAdA” or “BSHKK from Bishkek, the capital of KyrgyzstAn” also be valid solutions?
[The point is that the sequence is in alphabetic order of vowels and you need the capital of a country whose name only contains the vowel U. Cyprus is the only option here. The country names that contain only one vowel are, I think,
Bahamas
Canada
Chad
Ghana
Panama
Qatar
Rwanda
Japan
Kyrgyzstan
Kazakhstan
Madagascar
MaltaSeychelles
Sweden
Egypt
Greece
YemenFiji
Kosovo
Morocco
Togo
ComorosCyprus
Does that makes sense? Harry]
For Challenge 16 [yes, you have found the the missing terms, well done! Harry]
6th July 2020 at 11:00 am #49502Inactive@Harry – Ahhh that makes total sense, thanks for explaining – I hadn’t spotted the A-E-I-O-U pattern! Very clever!!
9th July 2020 at 3:13 pm #49522InactiveFor challenge 16,
{….]
(but I think I might be being a bit too obvious…?) [Right though! Harry]
18 mins, using Harry’s Hint9th July 2020 at 3:14 pm #4952310degrees-adminKeymasterI don’t get Challenge 16…
[Tricky isn’t it! Harry]
12th July 2020 at 9:35 am #49542InactiveIt depends on whether the letters are allowed to cycle, in order that each string is the same length
[Well done! Harry]
14th July 2020 at 10:18 am #4955110degrees-adminKeymasterThe answer is [Well, done, and yes we will! Thank you. Harry]
14th July 2020 at 10:22 am #4955510degrees-adminKeymasterFor 17 I have [The right answer, Harry] I feel even sillier for solving this one than […. I did consider combining them, but …. Harry]
17th July 2020 at 4:15 pm #49564InactiveFor challenge [Yep! Harry]
