Ques:Answer the following question given this paragraph: Lymph that collects in tissues slowly passes into tiny lymph vessels. Lymph then travels from smaller to larger lymph vessels. Muscles around the lymph vessels contract and squeeze the lymph through the vessels. The lymph vessels also contract to help move the lymph along. Eventually, lymph reaches the main lymph vessels, which are located in the chest. From these vessels, lymph drains into two large veins of the cardiovascular system. This is how lymph returns to the blood. Q: Which part of the wave helps make the wave bend and cause refraction? Choices: - dense part - heavy part - bright part - shallow part A:

Ans:
shallow part
