In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: From what era, once thought devoid of animal life, was evidence of grazer populations discovered?, Context: Some paleontologists suggest that animals appeared much earlier than the Cambrian explosion, possibly as early as 1 billion years ago. Trace fossils such as tracks and burrows found in the Tonian period indicate the presence of triploblastic worms, like metazoans, roughly as large (about 5 mm wide) and complex as earthworms. During the beginning of the Tonian period around 1 billion years ago, there was a decrease in Stromatolite diversity, which may indicate the appearance of grazing animals, since stromatolite diversity increased when grazing animals went extinct at the End Permian and End Ordovician extinction events, and decreased shortly after the grazer populations recovered. However the discovery that tracks very similar to these early trace fossils are produced today by the giant single-celled protist Gromia sphaerica casts doubt on their interpretation as evidence of early animal evolution.
[A]: the Tonian period

[Q]: Who may be more likely to have female clergy?, Context: Wesleyan theology stands at a unique cross-roads between evangelical and sacramental, between liturgical and charismatic, and between Anglo-Catholic and Reformed theology and practice. It has been characterized as Arminian theology with an emphasis on the work of the Holy Spirit to bring holiness into the life of the participating believer. The United Methodist Church believes in prima scriptura, seeing the Holy Bible as the primary authority in the Church and using sacred tradition, reason, and experience to interpret it, with the aid of the Holy Spirit (see Wesleyan Quadrilateral). Therefore, according to The Book of Discipline, United Methodist theology is at once "catholic, evangelical, and reformed." Today, the UMC is generally considered one of the more moderate and tolerant denominations with respect to race, gender, and ideology, though the denomination itself actually includes a very wide spectrum of attitudes. Comparatively, the UMC stands to the right of liberal and progressive Protestant groups such as the United Church of Christ and the Episcopal Church on certain issues (especially regarding sexuality), but to the left of historically conservative evangelical traditions such as the Southern Baptists and Pentecostalism, in regard to theological matters such as social justice and Biblical interpretation. However, it should be noted that the UMC is made up of a broad diversity of thought, and so there are many clergy and laity within the UMC that hold differing viewpoints on such theological matters.
[A]: United Church of Christ and the Episcopal Church

[Q]: Why does dialect continua cause issues with mutual intelligibility?, Context: The most common, and most purely linguistic, criterion is that of mutual intelligibility: two varieties are said to be dialects of the same language if being a speaker of one variety confers sufficient knowledge to understand and be understood by a speaker of the other; otherwise, they are said to be different languages. However, this definition becomes problematic in the case of dialect continua, in which it may be the case that dialect B is mutually intelligible with both dialect A and dialect C but dialects A and C are not mutually intelligible with each other. In this case the criterion of mutual intelligibility makes it impossible to decide whether A and C are dialects of the same language or not. Cases may also arise in which a speaker of dialect X can understand a speaker of dialect Y, but not vice versa; the mutual intelligibility criterion flounders here as well.
[A]:
makes it impossible to decide whether A and C are dialects of the same language or not
