Gorton maintained good relations with the United States and Britain, but pursued closer ties with Asia. The Gorton government experienced a decline in voter support at the 1969 election. State Liberal leaders saw his policies as too Centralist, while other Liberals didn't like his personal behaviour. In 1971, Defence Minister Malcolm Fraser, resigned and said Gorton was "not fit to hold the great office of Prime Minister". In a vote on the leadership the Liberal Party split 50/50, and although this was insufficient to remove him as the leader, Gorton decided this was also insufficient support for him, and he resigned.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who commented that Gorton was not fit to have voter support?
Ah, so.. unanswerable

Question: Gay and lesbian people can have sexual relationships with someone of the opposite sex for a variety of reasons, including the desire for a perceived traditional family and concerns of discrimination and religious ostracism. While some LGBT people hide their respective orientations from their spouses, others develop positive gay and lesbian identities while maintaining successful heterosexual marriages. Coming out of the closet to oneself, a spouse of the opposite sex, and children can present challenges that are not faced by gay and lesbian people who are not married to people of the opposite sex or do not have children.
Try to answer this question if possible: What is one reason that a homosexual would engage in heterosexual behavior?
Answer: religious ostracism

Question: In addition to re-writing the classification of annelids and 3 previously independent phyla, the molecular phylogenetics analyses undermine the emphasis that decades of previous writings placed on the importance of segmentation in the classification of invertebrates. Polychaetes, which these analyses found to be the parent group, have completely segmented bodies, while polychaetes' echiurans and sipunculan offshoots are not segmented and pogonophores are segmented only in the rear parts of their bodies. It now seems that segmentation can appear and disappear much more easily in the course of evolution than was previously thought. The 2007 study also noted that the ladder-like nervous system, which is associated with segmentation, is less universal previously thought in both annelids and arthropods.[n 2]
Try to answer this question if possible: How many previously-separate phyla did the 1837 study reclassify?
Answer:
unanswerable
