The truth about the psychic powers of groundhogs

Self-study activity:
Watch this video from How stuff works, which tries to address the question of whether groundhogs can really predict when spring will arrive or this is just an urban legend.

Some of the vocabulary in the video is quite advanced, but Básico 2 students (elementary) will find it possible to understand the words missing in the transcript below.

Like all marmots, a groundhog responds to the (8) ... changes in light and temperature that signal the (9) ... of spring. So you could say that, in a way, the groundhog is a bucktooth barometer.

But in Punxsutawney, they’re not terribly interested in the (10) ... of Phil’s predictions. That’s because this furry forecaster is a marmot, not a meteorologist.
