This week’s question is a bit more straightforward that the previous ones. There’s less of a “point” to these questions; they’re more of a trivia contest. I think they’re fun — and tricky — so let’s see how it goes.

In “one of these things is not like the other” style, for each group below tell me which item doesn’t belong, and (more importantly) why:

1. Specifications:

  1. WSDL
  2. Atom Publishing Protocol
  3. RDF
  4. WS-Policy

2. HTTP methods:

  1. GET
  2. PUT
  3. POST
  4. HEAD

3. MD5 hashes:

  1. f97c5d29941bfb1b2fdab0874906ab82
  2. d41d8cd98f00b204e9800998ecf8427e
  3. 35d6d33467aae9a2e3dccb4b6b027878
  4. 0495651fa03c897470784990f33d86cd

4. Programming languages:

  1. Erlang
  2. Ada
  3. Haskell
  4. Python

5. HTML 4 elements:

  1. <Q>
  2. <U>
  3. <I>
  4. <A>

As usual, tune in this weekend for the answers.
