I found numerous answers to the question...
Does the particle "を" (wo) have a special use when at the end of a sentence?
One comment says:
It's like Japanese color-by-numbers: the outline is there, but you have to pick your own verb to finish the picture.
My question is, to continue the analogy in the comment: among the crayons in the box, which verb (or verbs) does a native speaker choose to associate with the <を> in the following phrases? Clearly, not all verbs will work equally well; there must be a short list of possibilities.
より甘【あま】く、より大【おお】きく、日本一【にっぽんいち】の味【あじ】を
Sweeter, bigger, and the best taste in Japan.
