Suppose, in the North, One Unit of Labor Produces $f _ { n }$

True/False

Suppose, in the North, one unit of labor produces $f _ { n }$
units of fish or $c _ { n }$
units of chips. In the South, one unit of labor produces $f _ { s }$
units of fish and $c _ {s }$
units of chips. For the South to specialize in fish, it must be that $\left( f _ { s } / c _ { s } \right) < \left( f _ { n } / c _ { n } \right)$
