A supplement of Vitamin $A$ and Zinc may boost children's resistance to Malaria (observation from one experiment conducted last year in a village $’X’$). Which of the following, if true, would weaken the statement?

1. No adult in village $’X’$ has fallen sick because of Malaria.
2. Last three years there is hardly any case of child affected by Malaria from village $'X'$.
3. The experiment with Vitamin $A$ and Zinc is being duplicated in other nearby cities adjacent to village $’X’$.
4. Vitamin $A$ and Zinc are readily available in village $'X'$.

because there is already availability of vitamin A and zinc so the people from village X don't need the supplement.
