Problem: Predation:

The act of predation can be broken down into a maximum of four stages: Detection of prey, attack, capture and finally consumption. The relationship between predator and prey is one that is typically beneficial to the predator, and detrimental to the prey species. Sometimes, however, predation has indirect benefits to the prey species, though the individuals preyed upon themselves do not benefit. This means that, at each applicable stage, predator and prey species are in an evolutionary arms race to maximize their respective abilities to obtain food or avoid being eaten. This interaction has resulted in a vast array of adaptations in both groups.

In predation's four stages, in what stage is consumption?

A: final


Problem: In response to attribution of recent climate change, the City of Melbourne, in 2002, set a target to reduce carbon emissions to net zero by 2020 and Moreland City Council established the Zero Moreland program, however not all metropolitan municipalities have followed, with the City of Glen Eira notably deciding in 2009 not to become carbon neutral. Melbourne has one of the largest urban footprints in the world due to its low density housing, resulting in a vast suburban sprawl, with a high level of car dependence and minimal public transport outside of inner areas. Much of the vegetation within the city are non-native species, most of European origin, and in many cases plays host to invasive species and noxious weeds. Significant introduced urban pests include the common myna, feral pigeon, brown rat, European wasp, common starling and red fox. Many outlying suburbs, particularly towards the Yarra Valley and the hills to the north-east and east, have gone for extended periods without regenerative fires leading to a lack of saplings and undergrowth in urbanised native bushland. The Department of Sustainability and Environment partially addresses this problem by regularly burning off. Several national parks have been designated around the urban area of Melbourne, including the Mornington Peninsula National Park, Port Phillip Heads Marine National Park and Point Nepean National Park in the south east, Organ Pipes National Park to the north and Dandenong Ranges National Park to the east. There are also a number of significant state parks just outside Melbourne. Responsibility for regulating pollution falls under the jurisdiction of the EPA Victoria and several local councils. Air pollution, by world standards, is classified as being good. Summer and autumn are the worst times of year for atmospheric haze in the urban area.
Does Melbourne have one of the largest or smallest carbon footprints in the world?

Answer: largest

Early progress toward the development of vaccines occurred throughout this period, primarily in the form of academic and government-funded basic research directed toward the identification of the pathogens responsible for common communicable diseases. In 1885 Louis Pasteur and Pierre Paul Émile Roux created the first rabies vaccine. The first diphtheria vaccines were produced in 1914 from a mixture of diphtheria toxin and antitoxin (produced from the serum of an inoculated animal), but the safety of the inoculation was marginal and it was not widely used. The United States recorded 206,000 cases of diphtheria in 1921 resulting in 15,520 deaths. In 1923 parallel efforts by Gaston Ramon at the Pasteur Institute and Alexander Glenny at the Wellcome Research Laboratories (later part of GlaxoSmithKline) led to the discovery that a safer vaccine could be produced by treating diphtheria toxin with formaldehyde. In 1944, Maurice Hilleman of Squibb Pharmaceuticals developed the first vaccine against Japanese encephelitis. Hilleman would later move to Merck where he would play a key role in the development of vaccines against measles, mumps, chickenpox, rubella, hepatitis A, hepatitis B, and meningitis.
What company did Hilleman later work for?
A: Merck


Context and question: Because of its neutrality, Yugoslavia would often be rare among Communist countries to have diplomatic relations with right-wing, anti-Communist governments. For example, Yugoslavia was the only communist country allowed to have an embassy in Alfredo Stroessner's Paraguay. One notable exception to Yugoslavia's neutral stance toward anti-communist countries was Chile under Pinochet; Yugoslavia was one of many countries which severed diplomatic relations with Chile after Salvador Allende was overthrown. Yugoslavia also provided military aid and arms supplies to staunchly anti-Communist regimes such as that of Guatemala under Kjell Eugenio Laugerud García.
Who did Pinochet overthrow?
Answer: Allende


Question: Czech distinguishes three genders—masculine, feminine, and neuter—and the masculine gender is subdivided into animate and inanimate. With few exceptions, feminine nouns in the nominative case end in -a, -e, or -ost; neuter nouns in -o, -e, or -í, and masculine nouns in a consonant. Adjectives agree in gender and animacy (for masculine nouns in the accusative or genitive singular and the nominative plural) with the nouns they modify. The main effect of gender in Czech is the difference in noun and adjective declension, but other effects include past-tense verb endings: for example, dělal (he did, or made); dělala (she did, or made) and dělalo (it did, or made).
Is there an answer to this question: What is the main effect of consonants in Czech?

Answer: unanswerable

Of the 10 most populous U.S. cities, Houston has the most total area of parks and green space, 56,405 acres (228 km2). The city also has over 200 additional green spaces—totaling over 19,600 acres (79 km2) that are managed by the city—including the Houston Arboretum and Nature Center. The Lee and Joe Jamail Skatepark is a public skatepark owned and operated by the city of Houston, and is one of the largest skateparks in Texas consisting of 30,000 (2,800 m2) square foot in-ground facility. The Gerald D. Hines Waterwall Park—located in the Uptown District of the city—serves as a popular tourist attraction, weddings, and various celebrations. A 2011 study by Walk Score ranked Houston the 23rd most walkable of the 50 largest cities in the United States. Wet'n'Wild SplashTown is a water park located north of Houston.
What is one of the largest skate parks in Texas?
A:
The Lee and Joe Jamail Skatepark
