Level: 
A
Compare two definite integrals \( I_1 = \int\limits_0^5 0.6x\,\mathrm{d}x \) and \( I_2 = \int\limits_0^5 1.8x\,\mathrm{d}x \).
\( I_2 \) is \( 3 \) times as big as \( I_1 \).
\( I_1 \) is \( 3 \) times as big as \( I_2 \).
\( I_2 \) is \( 1.2 \) multiple of \( I_1 \).
\( I_2 \) is \( 30 \) times as big as \( I_ 1 \).

Compare two definite integrals \( I_1 = \int\limits_1^2 \frac1x\,\mathrm{d}x \) and \( I_2 = \int\limits_2^4 \frac1x\,\mathrm{d}x \).
\( I_1 \) is equal to \( I_2 \).
\( I_2 \) is twice as big as \( I_1 \).
\( I_1 \) is twice as big as \( I_2 \).
\( I_1 \) is \( 4 \) times as big as \( I_2 \).
