Short Answer 
The answer outlines three steps for using conjunctions and punctuation to clarify relationships between ideas. Step 1 emphasizes using “but” for contrasting ideas, Step 2 suggests “for” or “and” for connecting similar thoughts, and Step 3 recommends using a semicolon for related but distinct complete ideas.
Step 1: Identify Contrasting Ideas
When you have two ideas that contrast each other, you need a conjunction that reflects this. The word but is perfect for this purpose. It clearly shows that the second idea opposes the first, creating a clear distinction between the two thoughts.
Step 2: Understand Connecting Ideas
If you want to elaborate on a first idea with a second one that doesn’t necessarily oppose it, you might consider words like for. However, if you just need to connect related thoughts, and can seamlessly tie them together. This shows a relationship without implying contrast.
Step 3: Use Semicolons for Complete Ideas
When you have two complete ideas that are related but distinct, a semicolon is your best choice. This punctuation mark allows you to combine these thoughts effectively, indicating a connection while maintaining their individual integrity, resulting in a clearer message.
