Answer:
private saving would rise and national saving falls
Explanation:
private saving is income - consumptiioon= Y-C
if consumption c falls, private saving is going ton rise
public saving is T-G
as G goes up, T-G which is public saving would reduce or fall.
Given that the fall in c is smaller than the rise in G, the rise in private saving would smaller than the fall in public saving.
national saving is change in private saving + change in public saving
given that change in private saving is less than that of public saving, national saving would be negative.
