Answer:
1 If you see my love aging, work against it.
Step-by-step explanation:
Sonnet 100 is describing how during the previous time writer and his Muse were not so close, but still the writer warns his muse to remember that he should defy the consequences of time, and clearly states that in the third quatrain:
Rise, resty Muse, my love's sweet face survey,
If Time have any wrinkle graven there;
If any, be a satire to decay,
And make Time's spoils despised every where.
In the beginning of the quatrain, the writer says "Rise", which urges the Muse to a positive action of defeating time. Using vocabulary such as "be satire to decay" and "make Time's spoils despised" emphasises the point of this defying. Time spoils could be any consequences of time, like wrinkles, worries or even death.
