How to draw this mechanism

Fill in box with major and minor products

Hello, I do not understand this questions and I am stuck. May I get help please?? Question: Draw the curved arrow mechanism for the following reaction

if Therapeutic index increase，does it means that it cause higher death rate？？

Examine the curved arrow mechanism below, and answer the question in the box. If the mechanism is reasonable, draw all products. If the mechanism is not reasonable leave the drawing space blank. Is the curved arrow mechanism reasonable? O yes O no Click and drag to start drawing a structure. ?圖 图 ola Ar
