Problem: Please answer a question about the following article about Norfolk Island:
As a relatively small and isolated oceanic island, Norfolk has few land birds but a high degree of endemicity among them. Many of the endemic species and subspecies have become extinct as a result of massive clearance of the island's native vegetation of subtropical rainforest for agriculture, hunting and persecution as agricultural pests. The birds have also suffered from the introduction of mammals such as rats, cats, pigs and goats, as well as from introduced competitors such as common blackbirds and crimson rosellas.
What non-bird animals caused the bird populations of Norfolk Island to suffer?
A: mammals
Problem: Please answer a question about the following article about Chihuahua (state):
The uneasy alliance of Carranza, Obregon, Villa, and Zapata eventually led the rebels to victory. The fight against Huerta formally ended on August 15, 1914, when Alvaro Obregon signed a number of treaties in Teoloyucan in which the last of Huerta's forces surrendered to him and recognized the constitutional government.

In which city did Obregon sign a number of treaties?
A: Teoloyucan
Problem: Please answer a question about the following article about Insect:
The majority of insects hatch from eggs. The fertilization and development takes place inside the egg, enclosed by a shell (chorion) that consists of maternal tissue. In contrast to eggs of other arthropods, most insect eggs are drought resistant. This is because inside the chorion two additional membranes develop from embryonic tissue, the amnion and the serosa. This serosa secretes a cuticle rich in chitin that protects the embryo against desiccation. In Schizophora however the serosa does not develop, but these flies lay their eggs in damp places, such as rotting matter. Some species of insects, like the cockroach Blaptica dubia, as well as juvenile aphids and tsetse flies, are ovoviviparous. The eggs of ovoviviparous animals develop entirely inside the female, and then hatch immediately upon being laid. Some other species, such as those in the genus of cockroaches known as Diploptera, are viviparous, and thus gestate inside the mother and are born alive.:129, 131, 134135 Some insects, like parasitic wasps, show polyembryony, where a single fertilized egg divides into many and in some cases thousands of separate embryos.:136137 Insects may be univoltine, bivoltine or multivoltine, i.e. they may have one, two or many broods (generations) in a year.
Chorion is another word for what?
A: shell
