Read the Distribution Map of Twenty-four Solar Terms (Figure A) and the Variation Map of Terminal Line and Latitude Tangent Point in the Northern Hemisphere (Figure B), and complete questions 7-8. The following questions are relevant. A. There are two possibilities during the period from ① to ②: summer solstice to autumnal equinox or winter solstice to vernal equinox, which does not meet the meaning of the question;

B. There are two possibilities from ① to ②: If it is from summer solstice to autumnal equinox, it is correct that the midday sun height angle in Haikou first increases (to 90) and then decreases;

C. Because Jorge Nello is located at 22 s, its midday sun height angle can't reach the maximum value within one year from the bisector to the solar terms, and it directly reaches the maximum value at 22 s, which doesn't meet the meaning of the question;

D: ① The length of the day in Jingzhou, Hubei Province reaches an extreme value (maximum or minimum) in the solar terms, and ② the time is equal to day and night, which does not meet the meaning of the question.

Therefore, choose: B.
