Final answer:
Two cause and effect relationships from the book 'The War That Saved My Life' are the evacuation of Ada and Jamie from London, which leads to a change in their lives, and the impact of war on Ada's self-esteem and Jamie's maturity.
Step-by-step explanation:
In the book The War That Saved My Life by Kimberly Brubaker Bradley, two cause and effect relationships can be identified.
One cause is the main character, Ada, and her brother Jamie being evacuated from London during World War II. The effect of this is that their lives dramatically change as they are taken to the countryside and placed in the care of Susan Smith, who provides them with love, support, and a safe home.
Another cause is the war itself, which leads to other effects such as Ada's improved self-esteem and sense of independence as she learns to walk and ride a horse, and Jamie's growth and maturity as he becomes more responsible and protective of his sister.
