Can we draw the following hypothesis from the context (see options)?

Context:

By Lindsey Stewart Last week, residents of Chambers County experienced a once-in-a-lifetime weather event when record low temperatures combined with snow and ice to shutdown schools, businesses and roads in the area. Some parts of the county recorded temps with windchill that were near zero. Other areas measured snow up to six inches. We asked readers to send in their winter pictures and he is a sampling.

Hypothesis: 100 years ago it was warmer in Chambers County than it was the week before this week
Choices:
I. Yes
II. It's impossible to say
III. No
I.
