The correct answer is false.
It is false that Government websites are always unbiased and nonpartisan.
The US government should serve all the citizens of the United States, not only to the people who voted for any determined candidate. When the winning candidate became President of the United States, he is no more Republican or Democrat. He is American and as the head of the executive department, he, his cabinet members and all other government officials must show no biases. However, the way many of these website write information tend to bias information in favor of the present administration.
