text_A: Average daytime highs are in the mid 70s°F to low 80s°F (24–28°C) throughout the state in July, with overnight lows in the mid 50s°F to low 60s°F (13–15°C). January temperatures range from an average high of on the coast to overnight lows below in the far north and at high elevations. Average annual precipitation statewide is roughly with some variation occurring in the White Mountains due to differences in elevation and annual snowfall. New Hampshire's highest recorded temperature was in Nashua on July 4, 1911, while the lowest recorded temperature was atop Mount Washington on January 29, 1934. Mount Washington's 1934 low temperature reading was made official, and tied the all-time record low for New England that was set just weeks earlier on December 30, 1933 in Bloomfield, Vermont, and would not be tied again until an unofficial reading was made at Big Black River, Maine.
text_B: If you could say with 100% certainty that even unofficial temperature records are completely reliable and truthful, and that no other extremes had been missed, when you read the passage through that lens, would you therefore conclude that the temperature at Mount Washington on January 22, 1885 must have been at least a little bit lower than it was at the same location on January 29, 1934?
NO.
