Problem: Please answer a question about the following article about Predation:
Mimicry is a related phenomenon where an organism has a similar appearance to another species. One such example is the drone fly, which looks a lot like a bee, yet is completely harmless as it cannot sting at all. Another example of batesian mimicry is the io moth, (Automeris io), which has markings on its wings that resemble an owl's eyes. When an insectivorous predator disturbs the moth, it reveals its hind wings, temporarily startling the predator and giving it time to escape. Predators may also use mimicry to lure their prey, however. Female fireflies of the genus Photuris, for example, copy the light signals of other species, thereby attracting male fireflies, which are then captured and eaten (see aggressive mimicry).
Which organism looks like a bee but cannot sting?
A: drone fly

Question: Read this and answer the question

UN forces retreated to Suwon in the west, Wonju in the center, and the territory north of Samcheok in the east, where the battlefront stabilized and held. The PVA had outrun its logistics capability and thus were unable to press on beyond Seoul as food, ammunition, and materiel were carried nightly, on foot and bicycle, from the border at the Yalu River to the three battle lines. In late January, upon finding that the PVA had abandoned their battle lines, General Ridgway ordered a reconnaissance-in-force, which became Operation Roundup (5 February 1951). A full-scale X Corps advance proceeded, which fully exploited the UN Command's air superiority, concluding with the UN reaching the Han River and recapturing Wonju.

How was the PVA transporting supplies at one point?
Answer: on foot and bicycle

Problem: The malaria problem seems to be compounded by the AIDS epidemic. Research has shown that in Namibia the risk of contracting malaria is 14.5% greater if a person is also infected with HIV. The risk of death from malaria is also raised by approximately 50% with a concurrent HIV infection. Given infection rates this large, as well as a looming malaria problem, it may be very difficult for the government to deal with both the medical and economic impacts of this epidemic. The country had only 598 physicians in 2002.
What is the risk of contracting malaria if an individual is already infected with HIV?
The answer is the following: 14.5% greater

Tuvalu participates in the Alliance of Small Island States (AOSIS), which is a coalition of small island and low-lying coastal countries that have concerns about their vulnerability to the adverse effects of global climate change. Under the Majuro Declaration, which was signed on 5 September 2013, Tuvalu has commitment to implement power generation of 100% renewable energy (between 2013 and 2020), which is proposed to be implemented using Solar PV (95% of demand) and biodiesel (5% of demand). The feasibility of wind power generation will be considered. Tuvalu participates in the operations of the Pacific Islands Applied Geoscience Commission (SOPAC) and the Secretariat of the Pacific Regional Environment Programme (SPREP).
By what means does Tuvalu plan to produce 95% of its energy?
Solar PV
