Option 1 suggests that Republicans won the majority in the 2006 U.S. House of Representatives elections, which is incorrect. In 2006, it was the Democratic Party that won the majority in the House of Representatives, hence statement 1 is incorrect.

Option 2 states that Bobby Jindal, a Republican, won a seat in the U.S. House of Representatives for the second time. This is correct as Bobby Jindal was re-elected to the House in the 2006 elections, hence statement 2 is correct.

Option 3 suggests that both statements are correct, but as already noted, only statement 2 is correct.

Option 4 implies that neither of the statements is correct. This is not true because statement 2 is correct.

Therefore, option 2 is the correct answer: only statement 2 is correct.
