Both countries could gain from trade at the same time, but term of trade is inconsequential for the distribution of the gains
Both countries could gain from trade at the same time, but the volume of the gains depends on terms of trade
Neither country could ever gain from trade since term of trade is depends on the distribution of the gains from trade
Both countries could gain from trade at the same time, and the volume of the gains does not depend on terms of trade

It takes the position that countries should ideally export materials and resources of which they have an excess, while proportionately importing those resources they need.
