A body cools in \( 7 \, \text{minutes} \) from \( 60^\circ \text{C} \) to \( 40^\circ \text{C} \). The temperature of the surrounding is \( 10^\circ \text{C} \). The temperature of the body after the next \( 7 \, \text{minutes} \) will be:
\( 28^\circ \text{C} \)
\( 32^\circ \text{C} \)
\( 30^\circ \text{C} \)
\( 34^\circ \text{C} \)
