QUES: The onset of the southwest monsoon is anticipated to reach Punjab by May, but since the early 1970s the weather pattern has been irregular. The spring monsoon has either skipped over the area or has caused it to rain so hard that floods have resulted. June and July are oppressively hot. Although official estimates rarely place the temperature above 46 C, newspaper sources claim that it reaches 51 C and regularly carry reports about people who have succumbed to the heat. Heat records were broken in Multan in June 1993, when the mercury was reported to have risen to 54 C. In August the oppressive heat is punctuated by the rainy season, referred to as barsat, which brings relief in its wake. The hardest part of the summer is then over, but cooler weather does not come until late October.

When was the record heat spike in Multan?
What is the answer?
ANS: June 1993

QUES: The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militiasfrequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.

In some decorative applications, wood with knots may be desirable to add visual interest. In applications where wood is painted, such as skirting boards, fascia boards, door frames and furniture, resins present in the timber may continue to 'bleed' through to the surface of a knot for months or even years after manufacture and show as a yellow or brownish stain. A knot primer paint or solution, correctly applied during preparation, may do much to reduce this problem but it is difficult to control completely, especially when using mass-produced kiln-dried timber stocks.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what stage of processing does knot primer need to be applied for maximum effectiveness?
Ah, so.. preparation
