OPTIONS:
- lungs
- pores
- diaphragm
- gills

Answer: gills

Problem: OPTIONS:
- by budding

Q: Answer the following question given this paragraph: Nearly all fish reproduce sexually, and most species have separate sexes. Those without separate sexes avoid self-fertilization by producing sperm and eggs at different times. Each fish typically produces a large number of gametes. In most fish species, fertilization takes place externally. These fish are oviparous . Eggs are laid and embryos develop outside the mother's body. In a minority of fish, including sharks, eggs develop inside the mother's body but without nourishment from the mother. These fish are ovoviviparous . Q: How do the vast majority of fish reproduce? A:
Answer: sexually

Problem:OPTIONS:
- skeletal system
- nervous system
- reproductive system
- immune system

Answer the following question given this paragraph: Immune system organs include bone marrow, the thymus gland, the spleen, and the tonsils. Each organ has a different job in the immune system. Q: Bone marrow, the thymus gland, the spleen, and the tonsils are organs in what body system? A:
****
A: immune system

Answer the following question given this paragraph: Each type of rock weathers in its own way. Certain types of rock are very resistant to weathering. Igneous rocks tend to weather slowly because they are hard. Water cannot easily penetrate them. Granite is a very stable igneous rock. Other types of rock are easily weathered because they dissolve easily in weak acids. Limestone is a sedimentary rock that dissolves easily. When softer rocks wear away, the more resistant rocks form ridges or hills. Q: Hard igneous rocks and easily dissolved sedimentary rocks respond very differently to what natural force? A:
OPTIONS:
- gravity
- sunlight
- evaporation
- weathering
weathering

Answer the following question given this paragraph: Ribosomes are produced in the nucleolus, and then transported to the cytoplasm. Ribosomes are made of ribosomal proteins, called ribonucleoproteins , and ribosomal RNA (rRNA). Each ribosome has two parts, a large and a small subunit, as shown in Figure below . The subunits are attached to each other. During translation, the smaller subunit binds to the mRNA, while the larger subunit binds to the tRNA with attached amino acids. When a ribosome finishes reading an mRNA molecule, the two ribosomal subunits disassociate. Q: Ribosomes are produced in the nucleolus, and then transported to the what? A:
OPTIONS:
- cerebellum
- nucleus
- cytoskeleton
- cytoplasm

Answer: cytoplasm

input with options: Answer the following question given this paragraph: The bottom of the ocean is called the benthic zone. It includes the sediments on the bottom of the ocean and the water just above it. Organisms living in this zone include clams and crabs. They may be few in number due to relatively scarce nutrients in this zone. Q: The bottom of the ocean is called what? A:
OPTIONS:
- Intertidal zone
- Final zone
- Demersal zone
- the benthic zone
output:
the benthic zone
