A Semi-colon(;) and a Colon(:) are both punctuation marks used in a sentence or phrase. A semi-colon is essentially used to bring together two independent clauses that are connected in a sentence. For example, I have a dance practice tomorrow; I can't make it to the show tonight. From this example, the two sentences can stand on their own (independent) but are separated by a semi-colon. It can join phrases by using a conjunctive verb. It is used to bring together complex clauses using a coordinating conjunction.

A colon is a supporting element in a sentence. It used to show that a sentence follows the other. Colons are used to keep apart two independent clauses. It can also be used in a sentence having quotations. For example, Mr. James said to me: "Never lose hope", Michael wanted to know more about these three topics: Business organization, Marketing, and Opportunity cost.

Given the above, "Pedro summarized the speech" and "serving your country is a noble cause" can stand on their own but are joined by a semi-colon.
