In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.

Input: Consider Input: passage: Estrogens are synthesized in all vertebrates as well as some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. The three major naturally occurring forms of estrogen in females are estrone (E1), estradiol (E2), and estriol (E3). Another type of estrogen called estetrol (E4) is produced only during pregnancy. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males compared to females, estrogens nevertheless also have important physiological roles in males.
 question: is there such a thing as natural estrogen?

Output: Yes


Input: Consider Input: passage: In 1873, the head of the abbey came to an agreement with a Parisian cheese-seller granting exclusive rights of distribution, and the cheese soon became popular. The abbey sought trade protection, and eventually (in 1959), sold the rights to a major creamery. The cheese is now produced in a factory; the characteristic smooth rind the result of a plastic-coated wrapper. The rind is edible, but is made of wax and detracts from the flavour of the cheese.
 question: can you eat the rind of port salut?

Output: Yes
