This justifies what answer for what question? Q & A:
Passage: Representatives and Delegates serve for two-year terms, while the Resident Commissioner serves for four years. The Constitution permits the House to expel a member with a two-thirds vote. In the history of the United States, only five members have been expelled from the House; in 1861, three were removed for supporting the Confederate states' secession: John Bullock Clark (D-MO), John William Reid (D-MO) and Henry Cornelius Burnett (D-KY). Michael Myers (D-PA) was expelled after his criminal conviction for accepting bribes in 1980, and James Traficant (D-OH) was expelled in 2002 following his conviction for corruption. The House also has the power to formally censure or reprimand its members; censure or reprimand of a member requires only a simple majority, and does not remove that member from office.

Question: Based on this passage, how many years is the term for a member of the house of representatives?
two - year
