Why did Margaret Sanger view birth control as a women's rights issue?

Sanger felt that in order for women to have a more equal footing in society and to lead healthier lives, they needed to be able to determine when to bear children. She also wanted to prevent so-called back-alley abortions, which were common at the time because abortions were illegal in the United States.

 d. Vincent van Gogh

Explanation: This work of art is so characteristic of Vincent Van Gogh.  

It's called Wheatfield with Crows, and it was painted in 1890. Some critics consider this work to be the highlight of van Gogh's creation. Van Gogh was known for his thick application of paint on canvas, which can be seen in this work too. This painting technique is called "impasto" from the Italian word mixture, and it represents such a densely applied paint that the layers, textures and brush strokes can be clearly seen on the canvas.
