Task: Question Answering
Input (English): Passage: Blastocyst -- The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass (ICM) which subsequently forms the embryo. The outer layer of the blastocyst consists of cells collectively called the trophoblast. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoele. The trophoblast gives rise to the placenta. The name ``blastocyst'' arises from the Greek βλαστός blastos (``a sprout'') and κύστις kystis (``bladder, capsule'').
Question: does the entire blastocyst develop into a fetus
