Question

read the sentences. glazing pottery can be tricky. the stunning results make the effort worthwhile. what should be included to best combine the sentences? ; , and , but when

Explanation:

To combine the two sentences, we need a conjunction that shows a contrast between "tricky" (negative aspect of glazing pottery) and "stunning results make the effort worthwhile" (positive aspect). The conjunction "but" is used to show contrast. A semicolon can separate two independent clauses, but it doesn't show the contrast as effectively. " , and" shows addition, not contrast. "when" is a subordinating conjunction used for time, which doesn't fit here. So the correct choice is ", but".

Answer:

, but
