$10\mathrm{.}48.$ Create a table that shows the relative magnitudes of the modulus of elasticity of steel to aluminum alloys, copper alloys, titanium alloys, rubber, and wood.

We are talking about relative magnitude, which means you need to take steel's $E$ divided by the E of Aluminum Alloys, then steel's E divided by the E of Copper Alloys and so on$.$

Put these RELATIVE MAGNITUDE in a sequential order, that would mean the strongest material listed first.
