Problem: In the International Phonetic Alphabet (IPA), aspirated consonants are written using the symbols for voiceless consonants followed by the aspiration modifier letter ⟨◌ʰ⟩, a superscript form of the symbol for the voiceless glottal fricative ⟨h⟩. For instance, ⟨p⟩ represents the voiceless bilabial stop, and ⟨pʰ⟩ represents the aspirated bilabial stop.
Written IPA consonants use symbols for what?
The answer is the following: voiceless consonants

Problem: In June, Truman became the first president to address the NAACP. His speech was a significant departure from traditional race relations in the United States. In front of 10,000 people at the Lincoln Memorial, the president left no doubt where he stood on civil rights. According to his speech, America had "reached a turning point in the long history of our country's efforts to guarantee freedom and equality to all our citizens…Each man must be guaranteed equality of opportunity." He proposed what black citizens had been calling for - an enhanced role of federal authority through the states. "We must make the Federal government a friendly, vigilant defender of the rights and equalities of all Americans. And again I mean all Americans.":40
Who was the first President to address the NAACP?
The answer is the following: Truman

Problem: Tucson's primary electrical power source is a coal and natural gas power-plant managed by Tucson Electric Power that is situated within the city limits on the south-western boundary of Davis-Monthan Air-force base adjacent to Interstate-10. The air pollution generated has raised some concerns as the Sundt operating station has been online since 1962 as is exempt from many pollution standards and controls due to its age. Solar has been gaining ground in Tucson with its ideal over 300 days of sunshine climate. Federal, state, and even local utility credits and incentives have also enticed residents to equip homes with solar systems. Davis-Monthan AFB has a 3.3 Megawatt (MW) ground-mounted solar photovoltaic (PV) array and a 2.7 MW rooftop-mounted PV array, both of which are located in the Base Housing area. The base will soon have the largest solar-generating capacity in the United States Department of Defense after awarding a contract on September 10, 2010, to SunEdison to construct a 14.5 MW PV field on the northwestern side of the base.
What does Tucson's main power plant use for fuel?
The answer is the following: coal and natural gas

Problem: The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo 4-stage metamorphosis (see holometabolism). Insects that undergo 3-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. The higher level relationship of the Hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22–28 in). The most diverse insect groups appear to have coevolved with flowering plants.
Insects growth is constrained by what?
The answer is the following:
the inelastic exoskeleton
