#### Answer

Using Adams's method, the shares are apportioned to each person as follows:
Person A is apportioned 19 shares.
Person B is apportioned 2 shares.
Person C is apportioned 3 shares.
Person D is apportioned 36 shares.

#### Work Step by Step

Using the modified divisor of $d = 108$, we can find the modified quota for each person.
Person A:
$modified~quota = \frac{contribution}{modified~divisor}$
$modified~quota = \frac{2013}{108}$
$modified~quota = 18.64$
Person B:
$modified~quota = \frac{contribution}{modified~divisor}$
$modified~quota = \frac{187}{108}$
$modified~quota = 1.73$
Person C:
$modified~quota = \frac{contribution}{modified~divisor}$
$modified~quota = \frac{290}{108}$
$modified~quota = 2.69$
Person D:
$modified~quota = \frac{contribution}{modified~divisor}$
$modified~quota = \frac{3862}{108}$
$modified~quota = 35.76$
Using Adams's method, we apportion the shares by rounding the modified quota up to the nearest whole number. The shares are apportioned to each person as follows:
Person A is apportioned 19 shares.
Person B is apportioned 2 shares.
Person C is apportioned 3 shares.
Person D is apportioned 36 shares.
Note that the sum of the apportioned shares is 60.
