Callaghan had been widely expected to call a general election in the autumn of 1978 when most opinion polls showed Labour to have a narrow lead. However he decided to extend his wage restraint policy for another year hoping that the economy would be in a better shape for a 1979 election. But during the winter of 1978–79 there were widespread strikes among lorry drivers, railway workers, car workers and local government and hospital workers in favour of higher pay-rises that caused significant disruption to everyday life. These events came to be dubbed the "Winter of Discontent".
What group of people never went on strike?
A: unanswerable

Many pesticides can be grouped into chemical families. Prominent insecticide families include organochlorines, organophosphates, and carbamates. Organochlorine hydrocarbons (e.g., DDT) could be separated into dichlorodiphenylethanes, cyclodiene compounds, and other related compounds. They operate by disrupting the sodium/potassium balance of the nerve fiber, forcing the nerve to transmit continuously. Their toxicities vary greatly, but they have been phased out because of their persistence and potential to bioaccumulate.:239–240 Organophosphate and carbamates largely replaced organochlorines. Both operate through inhibiting the enzyme acetylcholinesterase, allowing acetylcholine to transfer nerve impulses indefinitely and causing a variety of symptoms such as weakness or paralysis. Organophosphates are quite toxic to vertebrates, and have in some cases been replaced by less toxic carbamates.:136–137 Thiocarbamate and dithiocarbamates are subclasses of carbamates. Prominent families of herbicides include phenoxy and benzoic acid herbicides (e.g. 2,4-D), triazines (e.g., atrazine), ureas (e.g., diuron), and Chloroacetanilides (e.g., alachlor). Phenoxy compounds tend to selectively kill broad-leaf weeds rather than grasses. The phenoxy and benzoic acid herbicides function similar to plant growth hormones, and grow cells without normal cell division, crushing the plant's nutrient transport system.:300 Triazines interfere with photosynthesis.:335 Many commonly used pesticides are not included in these families, including glyphosate.
What essential plan funtion is interrupted by triazines?
A: photosynthesis

In the year 712, Muhammad bin Qasim, an Umayyad general, sailed from the Persian Gulf into Sindh in Pakistan and conquered both the Sindh and the Punjab regions along the Indus river. The conquest of Sindh and Punjab, in modern-day Pakistan, although costly, were major gains for the Umayyad Caliphate. However, further gains were halted by Hindu kingdoms in India in the battle of Rajasthan. The Arabs tried to invade India but they were defeated by the north Indian king Nagabhata of the Pratihara Dynasty and by the south Indian Emperor Vikramaditya II of the Chalukya dynasty in the early 8th century. After this the Arab chroniclers admit that the Caliph Mahdi "gave up the project of conquering any part of India."
To what dynasty did Vikramaditya II belong?
A: Pratihara

In March 2013, the Blackstone Group and Carl Icahn expressed interest in purchasing Dell. In April 2013, Blackstone withdrew their offer, citing deteriorating business. Other private equity firms such as KKR & Co. and TPG Capital declined to submit alternative bids for Dell, citing the uncertain market for personal computers and competitive pressures, so the "wide-open bidding war" never materialized. Analysts said that the biggest challenge facing Silver Lake would be to find an “exit strategy” to profit from its investment, which would be when the company would hold an IPO to go public again, and one warned “But even if you can get a $25bn enterprise value for Dell, it will take years to get out.”
What year did the Blackstone Group express interest in acquiring Dell?
A:
2013
