Final answer:
The false statement among the choices is B) During and after the Civil War, Texans refused to make changes in their economy, as Texas did undergo significant economic changes post-war.
Step-by-step explanation:
The statement that is FALSE among the given choices is: B) During and after the Civil War, Texans refused to make changes in their economy. After the Civil War, Texas, along with other Southern states, faced numerous challenges in the rebuilding and restructuring of its economy. While large plantations did face labor shortages due to the emancipation of enslaved people, as indicated in option A), the statement in option B) is incorrect because Texas did not refuse to make changes in its economy. Instead, Texas along with other Southern states underwent significant economic changes. Options C) and D) both hold true; Texas did recover relatively quickly after the Civil War compared to other Southern states, and the cattle industry did become an important industry in Texas after the war.
