Each question has two parts. The second part is the first part with the first letter removed.
Example: US President and a type of steak = Trump/rump

Word ladders (1): 10 questions

Questions 1 to 5 and 6-10 are separate groups. Each group gives a clue to a two-word phrase, or eight letter word made of two distinct parts, where each word or part has four letters (e.g. chat show, download, reindeer etc.). The five answers (or part thereof) in each group transform one word into the other, changing one letter at a time. For example, the answers in one group of questions might be; Hell – Hill – Fill – File – Fire for the two-word phrase hell-fire.

Add a letter, take a letter, change a letter: 20 questions

The first five questions are standard general knowledge. The answers to the next five questions are the first five answers (or part thereof) with a letter removed. The next five answers are the first five answers (or part thereof) with a letter added. The final five answers are the first five answers (or part thereof) with a letter changed. In the case of multiple word answers, the same word is modified in each of the groups of five questions. For example, the answer to a question in the first group might be Iron Age. The answer to a question in the second group might then be Ron Atkinson (letter removed), in the third Jeremy Irons (letter added), and in the fourth Tron (letter changed).
