According to the diagram, the secondary vulval precursor cell is determined by the absence of inhibitory signals from the anchor cells and the presence of the primary inducer. Thus, reducing the amount of primary inducer would lead to the conversion of the secondary vulval precursor cell into an epidermal cell. Adding or reducing the amount of a secondary inducer or adding a second anchor cell would not affect the fate of the secondary vulval precursor cell in this context.
