Problem:In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis, arch ( a) eonucleosynthesis, archonucleosynthesis, protonucleosynthesis and pal (a) eonucleosynthesis ) refers to the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, H, having a single proton as a nucleus) during the early phases of the Universe. Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the Big Bang, and is calculated to be responsible for the formation of most of the universe's helium as the isotope helium-4 (He), along with small amounts of the hydrogen isotope deuterium (H or D), the helium isotope helium-3 (He), and a very small amount of the lithium isotope lithium-7 (Li). In addition to these stable nuclei, two unstable or radioactive isotopes were also produced: the heavy hydrogen isotope tritium (H or T); and the beryllium isotope beryllium-7 (Be); but these unstable isotopes later decayed into He and Li, as above.

Based on this passage, where did helium come from the early universe?
Solution:OK... The relevant information to answer the above question is: Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the Big Bang, and is calculated to be responsible for the formation of most of the universe's helium as the isotope helium-4 (He), along with small amounts of the hydrogen isotope deuterium (H or D), the helium isotope helium-3 (He), and a very small amount of the lithium isotope lithium-7 (Li).
in the interval from roughly 10 seconds to 20 minutes after the Big Bang.

Problem:Context: A total of 113 Justices have served on the Supreme Court of the United States, the highest judicial body in the United States. Justices have life tenure, and so they serve until they die in office, resign or retire, or are impeached and removed from office (which has never happened; the one impeached Justice was acquitted). Among the current members of the Court, Associate Justice Anthony Kennedy is the longest-serving justice, with a tenure of 7004110440000000000 ♠ 11,044 days (7004110440000000000 ♠ 30 years, 86 days) as of May 15, 2018. For the 104 non-incumbent justices, the mean length of service was 6,112 days (16.7 years) with a standard deviation of 3,620 days (9.9 years). The median length of service was 5,740 days (15.7 years). Their period of service ranges from William O. Douglas's 13,358 days (7004133580000000000 ♠ 36 years, 209 days) on the Court to the 163-day tenure of Thomas Johnson.

Question: who is the longest serving justice currently on the supreme court?
Solution:OK... The relevant information to answer the above question is: Among the current members of the Court, Associate Justice Anthony Kennedy is the longest-serving justice, with a tenure of 7004110440000000000 ♠ 11,044 days (7004110440000000000 ♠ 30 years, 86 days) as of May 15, 2018.
