Final answer:
The appropriate correction for the sentence in bold is: 'It is the weirdest thing, but it happens every time I eat it.'
Step-by-step explanation:
The appropriate correction for the sentence in bold is: It is the weirdest thing, but it happens every time I eat it. The sentence should be in the present tense because the action of sneezing occurs every time the person eats the brand of chocolate. The correct verb form to use is 'happens' instead of 'happened' as it indicates a habitual action. By using the present tense, the sentence maintains consistency with the rest of the paragraph.
