Question 4 Which of the following statements explains a benefit of an alloy compared with a pure metal? A Alloys are often stronger than pure metals. B Alloys are often more expensive than pure metals. C Alloys are found in nature more readily than pure metals.

## Step 1<br />The problem is asking us to identify the correct statement that explains a benefit of an alloy compared to a pure metal. <br /><br />## Step 2<br />An alloy is a mixture of two or more metals or a metal and another element. Alloys are designed to have properties that are superior to the pure metals from which they are made. <br /><br />## Step 3<br />Looking at the options, option A states that "Alloys are often stronger than pure metals". This is indeed a benefit of alloys. Alloys are often stronger than pure metals because the atoms in an alloy are packed more tightly together than in a pure metal. This increased density makes the alloy stronger.<br /><br />## Step 4<br />Options B and C do not explain a benefit of an alloy. Option B states that "Alloys are often more expensive than pure metals", which is not a benefit. Option C states that "Alloys are found in nature more readily than pure metals", which is also not a benefit.
