Investigating the reasons Slavery was canceled. In 1807, British Parliament abrogated the purchasing and offering of slaves. Shockingly, until 1833-when all parts of subjugation were abrogated you were still permitted to claim a slave. This sickened people in general thus they made a stop to bondage.
The British economy was already weak after WW1, so when the US stock market crashed, taxes were put on foreign imports. The value of British exports were halved, and many areas went into poverty (unemployment more than doubled) so Britain devalued their pound in 1931, which made goods cheaper and improved their economy.
Your answer would be A (having fingerprints recorded).
hope it helps!
