Anne: Halley's Comet, now in a part of its orbit relatively far from the Sun, recently flared brightly enough to be seen by telescope. ██ █████ ███ ████ ████ ████████ ██ █████ ██ ███ ████ ███ ███ ███████ ██ ████ █ █████ ████ ██ ██████ ████████

Sue concludes that Anne’s position—that it must be unusual for a comet to flare visibly while far from the Sun—is “nonsense.” This is supported by Sue’s claim that such a flare was observed only once merely because comets far from the Sun are not usually observed. The exceptional event was thus closely tracking the specific comet which flared, not necessarily the flare itself.
Sue introduces a new consideration to undermine Anne’s claim that an event only rarely being seen means that the event itself must be rare. Instead, Sue suggests that the event is rarely seen simply because of a lack of observation.
Sue challenges Anne's reasoning by
pointing out that ██████ ███ ██ ███ ████ ██████████ ██ ███████████ █████
drawing attention to ██ █████████████ ███████ ███ ██ ██████ ██████
presenting evidence that ████████ ███████████ ██████ ████████
