    I don't understand the following question at all:

    Kaons were originally called strange because they are produced in one type of interaction and they decay through a different type of interaction.
    (i) In which type of interaction are they produced?
    (ii) Which type of interaction causes them to decay?
    (iii) In which type of interaction is strangeness always conserved?

    i) Strange quarks can only be produced in one interaction - the strong interaction. Hence, Kaons must be produced in the strong interaction.
    ii) They decay in the weak inteaction.
    iii) Strangeness is conserved in the strong interaction, but not always in the weak interaction.

    Do you have a CGP AS Physics guide? If so, read up on the "Strangeness" topic of Particle Physics.
