Article: From the German point of view, March 1941 saw an improvement. The Luftwaffe flew 4,000 sorties that month, including 12 major and three heavy attacks. The electronic war intensified but the Luftwaffe flew major inland missions only on moonlit nights. Ports were easier to find and made better targets. To confuse the British, radio silence was observed until the bombs fell. X- and Y-Gerät beams were placed over false targets and switched only at the last minute. Rapid frequency changes were introduced for X-Gerät, whose wider band of frequencies and greater tactical flexibility ensured it remained effective at a time when British selective jamming was degrading the effectiveness of Y-Gerät.

Question: How did the Germans confuse the British?
Ans: radio silence was observed until the bombs fell

The problem: Answer a question about this article:
The first notable, and historically important, book credited to a Bermudian was The History of Mary Prince, a slave narrative by Mary Prince. It is thought to have contributed to the abolition of slavery in the British Empire. Ernest Graham Ingham, an expatriate author, published his books at the turn of the 19th and 20th centuries. In the 20th century, numerous books were written and published locally, though few were directed at a wider market than Bermuda. (The latter consisted primarily of scholarly works rather than creative writing). The novelist Brian Burland (1931– 2010) achieved a degree of success and acclaim internationally. More recently, Angela Barry has won critical recognition for her published fiction.
What contribution to history is it believed the History of Mary Prince made?
****
The answer: thought to have contributed to the abolition of slavery in the British Empire


Problem: Please answer a question about the following article about Annelid:
The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychaetes. Annelids are considered members of the Lophotrochozoa, a "super-phylum" of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans.
Which subtype of annelids includes most marine worms?
A: polychaetes


Question: Read this and answer the question

The Weston Cadet (model 852 introduced in 1949), Direct Reading (model 853 introduced 1954) and Master III (models 737 and S141.3 introduced in 1956) were the first in their line of exposure meters to switch and utilize the meanwhile established ASA scale instead. Other models used the original Weston scale up until ca. 1955. The company continued to publish Weston film ratings after 1955, but while their recommended values often differed slightly from the ASA film speeds found on film boxes, these newer Weston values were based on the ASA system and had to be converted for use with older Weston meters by subtracting 1/3 exposure stop as per Weston's recommendation. Vice versa, "old" Weston film speed ratings could be converted into "new" Westons and the ASA scale by adding the same amount, that is, a film rating of 100 Weston (up to 1955) corresponded with 125 ASA (as per ASA PH2.5-1954 and before). This conversion was not necessary on Weston meters manufactured and Weston film ratings published since 1956 due to their inherent use of the ASA system; however the changes of the ASA PH2.5-1960 revision may be taken into account when comparing with newer ASA or ISO values.

What were updated Weston values based on?
Answer:
the ASA system
