<u>A ticket</u> IS NOT a musical instument, try to look for key words, in this case "instrumento" "musical" are words in Spanish which are very similar in English, and you can probably infer from them.
<u>Knitting</u>, ISN'T music. Again, here you've got "música" as a similar word to music, in English.
"Cuento" is a <u>story or tale</u>, and yes it can be oral or written.
<u>A composer</u> is a writer of music, not the main character of a play. Here, "compositor" is the key word, as it is similar Spanish-English, thus you can infer.
<u>To publish </u>it is an action and yes it is to talk in public or big groups.
