-<p>You are given two jugs with capacities <code>jug1Capacity</code> and <code>jug2Capacity</code> liters. There is an infinite amount of water supply available. Determine whether it is possible to measure exactly <code>targetCapacity</code> liters using these two jugs.</p>
-
-<p>If <code>targetCapacity</code> liters of water are measurable, you must have <code>targetCapacity</code> liters of water contained <strong>within one or both buckets</strong> by the end.</p>

+<p>You are given two jugs with capacities <code>x</code> liters and <code>y</code> liters. You have an infinite water supply. Return whether the total amount of water in both jugs may reach <code>target</code> using the following operations:</p>
 
 <ul>
-	<li>Fill any of the jugs with water.</li>
-	<li>Empty any of the jugs.</li>
-	<li>Pour water from one jug into another till the other jug is completely full, or the first jug itself is empty.</li>
+	<li>Fill either jug completely with water.</li>
+	<li>Completely empty either jug.</li>
+	<li>Pour water from one jug into another until the receiving jug is full, or the transferring jug is empty.</li>
 </ul>
