The "yo yo" in the opinion polls continued into 1992, though after November 1990 any Labour lead in the polls was rarely sufficient for a majority. Major resisted Kinnock's calls for a general election throughout 1991. Kinnock campaigned on the theme "It's Time for a Change", urging voters to elect a new government after more than a decade of unbroken Conservative rule. However, the Conservatives themselves had undergone a dramatic change in the change of leader from Thatcher to Major, at least in terms of style if not substance. From the outset, it was clearly a well-received change, as Labour's 14-point lead in the November 1990 "Poll of Polls" was replaced by an 8% Tory lead a month later.
How long had Labour ruled unbroken?
A: unanswerable

Mobbing can be an interspecies activity: it is common for birds to respond to mobbing calls of a different species. Many birds will show up at the sight of mobbing and watch and call, but not participate. It should also be noted that some species can be on both ends of a mobbing attack. Crows are frequently mobbed by smaller songbirds as they prey on eggs and young from these birds' nests, but these same crows will cooperate with smaller birds to drive away hawks or larger mammalian predators. On occasion, birds will mob animals that pose no threat.
What is one thing hawks do when they see mobbing?
A:
unanswerable
