The problem: Answer a question about this article:
Like any plucked instrument, mandolin notes decay to silence rather than sound out continuously as with a bowed note on a violin, and mandolin notes decay faster than larger stringed instruments like the guitar. This encourages the use of tremolo (rapid picking of one or more pairs of strings) to create sustained notes or chords. The mandolin's paired strings facilitate this technique: the plectrum (pick) strikes each of a pair of strings alternately, providing a more full and continuous sound than a single string would.
What is a plectrum?
****
The answer: pick


Problem: Please answer a question about the following article about Insect:
Insects play important roles in biological research. For example, because of its small size, short generation time and high fecundity, the common fruit fly Drosophila melanogaster is a model organism for studies in the genetics of higher eukaryotes. D. melanogaster has been an essential part of studies into principles like genetic linkage, interactions between genes, chromosomal genetics, development, behavior and evolution. Because genetic systems are well conserved among eukaryotes, understanding basic cellular processes like DNA replication or transcription in fruit flies can help to understand those processes in other eukaryotes, including humans. The genome of D. melanogaster was sequenced in 2000, reflecting the organism's important role in biological research. It was found that 70% of the fly genome is similar to the human genome, supporting the evolution theory.
Drosophila has helped develop principles in what kind of linkage?
A: genetic

Some international railway services to Continental Europe were operated during the 20th century as boat trains, such as the Admiraal de Ruijter to Amsterdam and the Night Ferry to Paris and Brussels. The opening of the Channel Tunnel in 1994 connected London directly to the continental rail network, allowing Eurostar services to begin. Since 2007, high-speed trains link St. Pancras International with Lille, Paris, Brussels and European tourist destinations via the High Speed 1 rail link and the Channel Tunnel. The first high-speed domestic trains started in June 2009 linking Kent to London. There are plans for a second high speed line linking London to the Midlands, North West England, and Yorkshire.

London is directly connected to continental Europe through what rail service?
Answer: Eurostar


Problem: The eusocial insects build nest, guard eggs, and provide food for offspring full-time (see Eusociality). Most insects, however, lead short lives as adults, and rarely interact with one another except to mate or compete for mates. A small number exhibit some form of parental care, where they will at least guard their eggs, and sometimes continue guarding their offspring until adulthood, and possibly even feeding them. Another simple form of parental care is to construct a nest (a burrow or an actual construction, either of which may be simple or complex), store provisions in it, and lay an egg upon those provisions. The adult does not contact the growing offspring, but it nonetheless does provide food. This sort of care is typical for most species of bees and various types of wasps.
What do eusocial insects guard?
The answer is the following: eggs


In 2004, madaris were mainstreamed in 16 Regions nationwide, primarily in Muslim-majority areas in Mindanao under the auspices of the Department of Education (DepEd). The DepEd adopted Department Order No. 51, which instituted Arabic-language and Islamic Values instruction for Muslim children in state schools, and authorised implementation of the Standard Madrasa Curriculum (SMC) in private-run madaris. While there are state-recognised Islamic schools, such as Ibn Siena Integrated School in the Islamic City of Marawi, Sarang Bangun LC in Zamboanga and SMIE in Jolo, their Islamic studies programmes initially varied in application and content.
When did madaris become more accepted in Mindanao?
2004


Here is a question about this article: Mali faces numerous health challenges related to poverty, malnutrition, and inadequate hygiene and sanitation. Mali's health and development indicators rank among the worst in the world. Life expectancy at birth is estimated to be 53.06 years in 2012. In 2000, 62–65 percent of the population was estimated to have access to safe drinking water and only 69 percent to sanitation services of some kind. In 2001, the general government expenditures on health totalled about US$4 per capita at an average exchange rate.
What is the answer to this question: In 2000 what percentage of the population had access to safe drinking water?
****
So...
62–65
