Shivaani - I think that all the code is asking you to do is to add another variable called doDisplay and an elseif that would check if this variable is true. If so, then you would plot the densities. So there would be two ways to plot the data - either through the doPlot or with the doDisplay
if doPlot
    plot(density)
    title("Sample Densities")
    xticklabels(element)
    ylabel("Density (g/cm^3)")
elseif doDisplay
    plot(density)
    title("Sample Densities")
    xticklabels(element)
    ylabel("Density (g/cm^3)") 
else
    disp("The density of " + element ...
        + " is " + density)
end
You would need to declare and initialize the doDisplay variable too.
