Question

how has the abolition of slavery in britain and the us affected the issue of global slavery up to the present day? it has reduced slavery worldwide, yet over thirty million people are still enslaved today. it has erased slavery from existence in all parts of the modern - day world. it has ended forced labor, but it has not eliminated other forms of slavery in the world today. it has shown no impact on the global effort to end slavery since colonial times.

Explanation:

The abolition of slavery in Britain and the US was a significant step that inspired other countries and movements, reducing the prevalence of slavery globally. However, modern - day forms of slavery, such as human trafficking for forced labor and sexual exploitation, still exist. The statement "It has reduced slavery worldwide, yet over thirty million people are still enslaved today" is in line with historical impact and current reality.
The claim that it "has erased slavery from existence in all parts of the modern - day world" is false as modern - day slavery persists. Forced labor is still a form of slavery, so the statement "It has ended forced labor..." is incorrect. And the abolition in Britain and the US did have an impact on the global anti - slavery movement, so the option "It has shown no impact..." is wrong.

Answer:

It has reduced slavery worldwide, yet over thirty million people are still enslaved today.
