International Trade problem about one-factor Ricardian Model with two countries and many goods.

Consider a world with two countries and three goods. Both countries can use linear labor-only technologies to produce these goods.

Assume that the equilibrium pattern of specialization is such that both countries produce strictly positive amounts of good 2.

Please help with the following.

The previous parts of the question may be needed. It's now updated in the picture. Thank you.

1. Consider a world with two countries and three goods. Both countries can use linear labor-only technologies to produce these goods. The labor productivities in the home country are denoted by Zn,H, and in the foreign country by Zn,F, where ne {1, 2,3}. These productivities are positive and satisfy 21.H 22.H 23.1 1. 1.
