Problem: Pesticide:

Some pesticides are considered too hazardous for sale to the general public and are designated restricted use pesticides. Only certified applicators, who have passed an exam, may purchase or supervise the application of restricted use pesticides. Records of sales and use are required to be maintained and may be audited by government agencies charged with the enforcement of pesticide regulations. These records must be made available to employees and state or territorial environmental regulatory agencies.

What needs to be kept about the sale of applicators?

Problem: When the British invaded the harbour town in 1744[verification needed], the town's architectural buildings were destroyed[verification needed]. Subsequently, new structures were built in the town around the harbour area[verification needed] and the Swedes had also further added to the architectural beauty of the town in 1785 with more buildings, when they had occupied the town. Earlier to their occupation, the port was known as "Carenage". The Swedes renamed it as Gustavia in honour of their king Gustav III. It was then their prime trading center. The port maintained a neutral stance since the Caribbean war was on in the 18th century. They used it as trading post of contraband and the city of Gustavia prospered but this prosperity was short lived.
In what year did the Caribbean war end?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Short-term memory is supported by transient patterns of neuronal communication, dependent on regions of the frontal lobe (especially dorsolateral prefrontal cortex) and the parietal lobe. Long-term memory, on the other hand, is maintained by more stable and permanent changes in neural connections widely spread throughout the brain. The hippocampus is essential (for learning new information) to the consolidation of information from short-term to long-term memory, although it does not seem to store information itself. Without the hippocampus, new memories are unable to be stored into long-term memory, as learned from patient Henry Molaison after removal of both his hippocampi, and there will be a very short attention span. Furthermore, it may be involved in changing neural connections for a period of three months or more after the initial learning.
Who had the removal of both of his lobes?
A: unanswerable

Context and question: Vacuum is useful in a variety of processes and devices. Its first widespread use was in the incandescent light bulb to protect the filament from chemical degradation. The chemical inertness produced by a vacuum is also useful for electron beam welding, cold welding, vacuum packing and vacuum frying. Ultra-high vacuum is used in the study of atomically clean substrates, as only a very good vacuum preserves atomic-scale clean surfaces for a reasonably long time (on the order of minutes to days). High to ultra-high vacuum removes the obstruction of air, allowing particle beams to deposit or remove materials without contamination. This is the principle behind chemical vapor deposition, physical vapor deposition, and dry etching which are essential to the fabrication of semiconductors and optical coatings, and to surface science. The reduction of convection provides the thermal insulation of thermos bottles. Deep vacuum lowers the boiling point of liquids and promotes low temperature outgassing which is used in freeze drying, adhesive preparation, distillation, metallurgy, and process purging. The electrical properties of vacuum make electron microscopes and vacuum tubes possible, including cathode ray tubes. The elimination of air friction is useful for flywheel energy storage and ultracentrifuges.
What are two things made possible by the electrical properties of vacuum?
Answer: electron microscopes and vacuum tubes

Question: In Singapore, madrasahs are private schools which are overseen by Majlis Ugama Islam Singapura (MUIS, English: Islamic Religious Council of Singapore). There are six Madrasahs in Singapore, catering to students from Primary 1 to Secondary 4. Four Madrasahs are coeducational and two are for girls. Students take a range of Islamic Studies subjects in addition to mainstream MOE curriculum subjects and sit for the PSLE and GCE 'O' Levels like their peers. In 2009, MUIS introduced the "Joint Madrasah System" (JMS), a joint collaboration of Madrasah Al-Irsyad Al-Islamiah primary school and secondary schools Madrasah Aljunied Al-Islamiah (offering the ukhrawi, or religious stream) and Madrasah Al-Arabiah Al-Islamiah (offering the academic stream). The JMS aims to introduce the International Baccalaureate (IB) programme into the Madrasah Al-Arabiah Al-Islamiah by 2019. Students attending a madrasah are required to wear the traditional Malay attire, including the songkok for boys and tudong for girls, in contrast to mainstream government schools which ban religious headgear as Singapore is officially a secular state. For students who wish to attend a mainstream school, they may opt to take classes on weekends at the madrasah instead of enrolling full-time.
Is there an answer to this question: What program is being installed in madrasahs in Singapore?

Answer: International Baccalaureate

As financial assets became more and more complex, and harder and harder to value, investors were reassured by the fact that both the international bond rating agencies and bank regulators, who came to rely on them, accepted as valid some complex mathematical models which theoretically showed the risks were much smaller than they actually proved to be. George Soros commented that "The super-boom got out of hand when the new products became so complicated that the authorities could no longer calculate the risks and started relying on the risk management methods of the banks themselves. Similarly, the rating agencies relied on the information provided by the originators of synthetic products. It was a shocking abdication of responsibility."
Who commented that the super-boom got out of hand when products became so complicated that risk could not be accurately calculated?
