__ 10. How should you begin constructing a block wall? a.build from the middle and work out b. lay one complete course of block the length of the wall c.build the comers first, several courses high d.start at the end that has a door

## Step 1<br />This problem is about the correct method of constructing a block wall. The options provided suggest different starting points for the construction process.<br /><br />## Step 2<br />Option A suggests starting from the middle and working outwards. This method could lead to difficulties in aligning the blocks and may result in an uneven wall.<br /><br />## Step 3<br />Option B suggests laying one complete course of blocks along the length of the wall. This method provides a solid base and ensures that the wall is straight.<br /><br />## Step 4<br />Option C suggests building the corners first, several courses high. This method could lead to difficulties in aligning the blocks and may result in an uneven wall.<br /><br />## Step 5<br />Option D suggests starting at the end that has a door. This method could lead to difficulties in aligning the blocks and may result in an uneven wall.<br /><br />## Step 6<br />Based on the analysis of each option, option B is the most appropriate method for starting the construction of a block wall.
