To determine whether each underlined clause is the main clause or a subordinate clause, you can follow these steps:

1. Identify the subject and verb of the underlined clause.
2. Determine if the underlined clause can stand alone as a complete sentence or if it depends on the main clause to make sense.

Let's apply these steps to each sentence:

Sentence 1: "We studied the Mayan calendar, (which I thought was fascinating)."
- Subject and verb of the underlined clause: "I thought"
- The underlined clause cannot stand alone as a complete sentence, so it depends on the main clause ("We studied the Mayan calendar") to make sense.
- The underlined clause is a subordinate clause.

Sentence 2: "Lyndon B. Johnson, (who was born in Stonewall,) became a president in 1963."
- Subject and verb of the underlined clause: "who was born"
- The underlined clause cannot stand alone as a complete sentence, so it depends on the main clause ("Lyndon B. Johnson became a president in 1963") to make sense.
- The underlined clause is a subordinate clause.

Sentence 3: "(I felt a thrill) when I solved the difficult math problem."
- Subject and verb of the underlined clause: "I felt"
- The underlined clause can stand alone as a complete sentence, expressing a complete thought.
- The underlined clause is the main clause.

Sentence 4: "After they played basketball (the boys went home for dinner)."
- Subject and verb of the underlined clause: "the boys went"
- The underlined clause can stand alone as a complete sentence, expressing a complete thought.
- The underlined clause is the main clause.

Sentence 5: "Hunter picked a report topic (that turned out to be difficult)."
- Subject and verb of the underlined clause: "that turned"
- The underlined clause cannot stand alone as a complete sentence, so it depends on the main clause ("Hunter picked a report topic") to make sense.
- The underlined clause is a subordinate clause.
