Problem: Ashkenazi Jews:

In the generations after emigration from the west, Jewish communities in places like Poland, Russia, and Belarus enjoyed a comparatively stable socio-political environment. A thriving publishing industry and the printing of hundreds of biblical commentaries precipitated the development of the Hasidic movement as well as major Jewish academic centers. After two centuries of comparative tolerance in the new nations, massive westward emigration occurred in the 19th and 20th centuries in response to pogroms in the east and the economic opportunities offered in other parts of the world. Ashkenazi Jews have made up the majority of the American Jewish community since 1750.

Massive western emigration occurred around what time?
---
A: in the 19th and 20th centuries

Problem: Royal Dutch Shell:

For various reasons, the new firm operated as a dual-listed company, whereby the merging companies maintained their legal existence, but operated as a single-unit partnership for business purposes. The terms of the merger gave 60 percent ownership of the new group to the Dutch arm and 40 percent to the British. National patriotic sensibilities would not permit a full-scale merger or takeover of either of the two companies. The Dutch company, Koninklijke Nederlandsche Petroleum Maatschappij, was in charge at The Hague of production and manufacture. A British company was formed, called the Anglo-Saxon Petroleum Company, based in London, to direct the transport and storage of the products.

What british company was in charge at The Hague?

A: unanswerable

It may also be classified as atopic or non-atopic where atopy refers to a predisposition toward developing a type 1 hypersensitivity reaction.
