Article: On March 13, 1969, on the Bái Háp River, Kerry was in charge of one of five Swift boats that were returning to their base after performing an Operation Sealords mission to transport South Vietnamese troops from the garrison at Cái Nước and MIKE Force advisors for a raid on a Vietcong camp located on the Rach Dong Cung canal. Earlier in the day, Kerry received a slight shrapnel wound in the buttocks from blowing up a rice bunker. Debarking some but not all of the passengers at a small village, the boats approached a fishing weir; one group of boats went around to the left of the weir, hugging the shore, and a group with Kerry's PCF-94 boat went around to the right, along the shoreline. A mine was detonated directly beneath the lead boat, PCF-3, as it crossed the weir to the left, lifting PCF-3 "about 2-3 ft out of water".

Question: What boat was Kerry on, on Mar 13?
Ans: PCF-94


Article: In 2012, resident foreigners made up 23.3% of the population. Most of these (64%) were from European Union or EFTA countries. Italians were the largest single group of foreigners with 15.6% of total foreign population. They were closely followed by Germans (15.2%), immigrants from Portugal (12.7%), France (5.6%), Serbia (5.3%), Turkey (3.8%), Spain (3.7%), and Austria (2%). Immigrants from Sri Lanka, most of them former Tamil refugees, were the largest group among people of Asian origin (6.3%). Additionally, the figures from 2012 show that 34.7% of the permanent resident population aged 15 or over in Switzerland, i.e. 2,335,000 persons, had an immigrant background. A third of this population (853,000) held Swiss citizenship. Four fifths of persons with an immigration background were themselves immigrants (first generation foreigners and native-born and naturalised Swiss citizens), whereas one fifth were born in Switzerland (second generation foreigners and native-born and naturalised Swiss citizens). In the 2000s, domestic and international institutions expressed concern about what they perceived as an increase in xenophobia, particularly in some political campaigns. In reply to one critical report the Federal Council noted that "racism unfortunately is present in Switzerland", but stated that the high proportion of foreign citizens in the country, as well as the generally unproblematic integration of foreigners", underlined Switzerland's openness.

Question: In 2010, what percentage of the population was made up of foreigners?
Ans: 23.3%


Article: In an operational capacity, limitations in weapons technology and quick British reactions were making it more difficult to achieve strategic effect. Attacking ports, shipping and imports as well as disrupting rail traffic in the surrounding areas, especially the distribution of coal, an important fuel in all industrial economies of the Second World War, would net a positive result. However, the use of delayed-action bombs, while initially very effective, gradually had less impact, partly because they failed to detonate.[c] Moreover, the British had anticipated the change in strategy and dispersed its production facilities making them less vulnerable to a concentrated attack. Regional commissioners were given plenipotentiary powers to restore communications and organise the distribution of supplies to keep the war economy moving.

Question: Coupled with British quick reactions what cause operational capacity hard to achieve?
Ans: limitations in weapons technology


Article: Although pest insects attract the most attention, many insects are beneficial to the environment and to humans. Some insects, like wasps, bees, butterflies and ants, pollinate flowering plants. Pollination is a mutualistic relationship between plants and insects. As insects gather nectar from different plants of the same species, they also spread pollen from plants on which they have previously fed. This greatly increases plants' ability to cross-pollinate, which maintains and possibly even improves their evolutionary fitness. This ultimately affects humans since ensuring healthy crops is critical to agriculture. As well as pollination ants help with seed distribution of plants. This helps to spread the plants which increases plant diversity. This leads to an overall better environment. A serious environmental problem is the decline of populations of pollinator insects, and a number of species of insects are now cultured primarily for pollination management in order to have sufficient pollinators in the field, orchard or greenhouse at bloom time.:240–243 Another solution, as shown in Delaware, has been to raise native plants to help support native pollinators like L. vierecki. Insects also produce useful substances such as honey, wax, lacquer and silk. Honey bees have been cultured by humans for thousands of years for honey, although contracting for crop pollination is becoming more significant for beekeepers. The silkworm has greatly affected human history, as silk-driven trade established relationships between China and the rest of the world.

Question: Many insects are what to the environment?
