Problem: Presbyterianism:

In the mainly Christian Indian state of Mizoram, the Presbyterian denomination is the largest denomination; it was brought to the region with missionaries from Wales in 1894. Prior to Mizoram, the Welsh Presbyterians (missionaries) started venturing into the north-east of India through the Khasi Hills (presently located within the state of Meghalaya in India) and established Presbyterian churches all over the Khasi Hills from the 1840s onwards. Hence there is a strong presence of Presbyterians in Shillong (the present capital of Meghalaya) and the areas adjoining it. The Welsh missionaries built their first church in Sohra (aka Cherrapunji) in 1846. Presbyterians participated in the mergers that resulted in the Church of North India and the Church of South India.Sohra

Problem: A cappella:

Contemporary a cappella includes many vocal groups and bands who add vocal percussion or beatboxing to create a pop/rock/gospel sound, in some cases very similar to bands with instruments. Examples of such professional groups include Straight No Chaser, Pentatonix, The House Jacks, Rockapella, Mosaic, and M-pact. There also remains a strong a cappella presence within Christian music, as some denominations purposefully do not use instruments during worship. Examples of such groups are Take 6, Glad and Acappella. Arrangements of popular music for small a cappella ensembles typically include one voice singing the lead melody, one singing a rhythmic bass line, and the remaining voices contributing chordal or polyphonic accompaniment.

What has maintained a strong presence in all types of worship?

A: unanswerable


Problem: New York City:

New York City has been described as the cultural capital of the world by the diplomatic consulates of Iceland and Latvia and by New York's Baruch College. A book containing a series of essays titled New York, culture capital of the world, 1940–1965 has also been published as showcased by the National Library of Australia. In describing New York, author Tom Wolfe said, "Culture just seems to be in the air, like part of the weather."

Problem: Wood:

The structure of hardwoods is more complex. The water conducting capability is mostly taken care of by vessels: in some cases (oak, chestnut, ash) these are quite large and distinct, in others (buckeye, poplar, willow) too small to be seen without a hand lens. In discussing such woods it is customary to divide them into two large classes, ring-porous and diffuse-porous.

In wood from a willow tree, what would you need to use to see the tiny vessels?
---
A:
a hand lens
