In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Passage: Altar 1 is found at the base of Stela 1. It is rectangular in shape with carved molding on its side.Altar 2 is of unknown provenance, having been moved to outside the administrator's house on the San Isidro Piedra Parada plantation. It is 1.59 metres (63 in) long, about 0.9 metres (35 in) wide and about 0.5 metres (20 in) high. It represents an animal variously identified as a toad and a jaguar. The body of the animal was sculptured to form a hollow 85 centimetres (33 in) across and 26 centimetres (10 in) deep. The sculpture was broken into three pieces.Altar 3 is a roughly worked flat, circular altar about 1 metre (39 in) across and 0.3 metres (12 in) high. It was probably associated originally with a stela but its original location is unknown, it was moved near to the manager's house on the San Isidro Piedra Parada plantation.Altar 5 is a damaged plain circular altar associated with Stela 2.Altar 7 is near the southern edge of the plaza on Terrace 3, where it is one of five monuments in a line running east-west.Altar 8 is a plain monument associated with Stela 5, positioned on the west side of Structure 12.Altar 9 is a low four-legged throne placed in front of Structure 11.Altar 10 was associated with Stela 13 and was found on top of the large offering of ceramics associated with that stela and the royal tomb in Structure 7A. The monument was originally a throne with cylindrical supports that was reused as an altar in the Classic period.Altar 12 is carved in the early Maya style and archaeologists consider it to be an especially early example dating to the first part of the Late Preclassic. Because of the carvings on the upper face of the altar, it is supposed that the monument was originally erected as a vertical stela in the Late Preclassic, and was reused as a horizontal altar in the Classic. At this time 16 hieroglyphs were carved around the outer rim of the altar. The carving on the upper face of the altar represents a standing human figure portrayed in profile, facing left. The figure is flanked by two vertical series of four glyphs. A smaller profile figure is depicted facing the first figure, separated from it by one of the series of glyphs. The central figure is depicted standing upon a horizontal band representing the earth, the band is flanked by two earth monsters. Above the figure is a celestial band with part of the head of a sacred bird visible in the centre. The 16 glyphs on the rim of the monument are formed by anthropomorphic figures mixed with other elements.
Question: What is carved on the outer rim of Altar 12 and are formed by anthropomorphic figures mixed with other elements?
16 hieroglyphs.

Passage: Following a life-threatening drug addiction that developed after leaving the Chili Peppers in 1992, Frusciante completed a month of drug rehabilitation at Las Encinas in Pasadena in 1998. Shortly thereafter he was asked to rejoin the band. After several months of writing and recording, the Chili Peppers' next album, Californication was released. The album went on to sell more than 15 million copies worldwide, becoming the Chili Peppers' most successful recording to date. Frusciante's return generated much response from critics, who recognized the album as a commercial revitalization from their previous record, One Hot Minute. A two-year-long, international tour followed, which included several festival appearances, including Woodstock 1999 and Rock in Rio.
The writing and formation of By the Way began immediately following the culmination of Californication's world tour, in the spring of 2001. As with Californication, much of the creation took place in the band members' homes and other practice locations, such as a recording studio stage. Kiedis recalled of the situation: "We started finding some magic and some music and some riffs and some rhythms and some jams and some grooves, and we added to it and subtracted from it and pushed it around and put melodies to it." Frusciante and Kiedis would collaborate for days straight, discussing guitar progressions and sharing lyrics. For Kiedis, "writing By the Way...was a whole different experience from Californication. John was back to himself and brimming with confidence." Prior to recording By the Way, the Chili Peppers decided that they would again have Rick Rubin produce the album. Rubin had, in the past, granted the Chili Peppers creative freedom on their recording material; this was something they thought essential for the album to be unique, and could only occur with his return.
Question: What was Frusciante asked to rejoin after rehab?
the Chili Peppers.

Passage: Mauna Kea is one of five volcanoes that form the island of Hawaii, the largest and youngest island of the HawaiianEmperor seamount chain. Of these five hotspot volcanoes, Mauna Kea is the fourth oldest and fourth most active. It began as a preshield volcano driven by the Hawaii hotspot around one million years ago, and became exceptionally active during its shield stage until 500,000 years ago. Mauna Kea entered its quieter post-shield stage 250,000 to 200,000 years ago, and is currently dormant. Mauna Kea does not have a visible summit caldera, but contains a number of small cinder and pumice cones near its summit. A former summit caldera may have been filled and buried by later summit eruption deposits.
Mauna Kea is over 32,000 km3 (7,680 cu mi) in volume, so massive that it and its neighbor, Mauna Loa, depress the ocean crust beneath it by 6 km (4 mi).
Mauna Kea is the only Hawaiian volcano with distinct evidence of glaciation. Similar deposits probably existed on Mauna Loa, but have been covered by later lava flows. Despite Hawaii's tropical location, during several past ice ages a drop of a degree in temperature allowed snow to remain at the volcano's summit through summer, triggering the formation of an ice cap. There are three episodes of glaciation that have been recorded from the last 180,000 years: the Pohakuloa (180130 ka), Waihu (8060 ka) and Makanaka (4013 ka) series. These have extensively sculpted the summit, depositing moraines and a circular ring of till and gravel along the volcano's upper flanks. Subglacial eruptions built cinder cones during the Makanaka glaciation, most of which were heavily gouged by glacial action. The most recent cones were built between 9000 and 4500 years ago, atop the glacial deposits, although one study indicates that the last eruption may have been around 3600 years ago.At their maximum extent, the glaciers extended from the summit down to between 3,200 and 3,800 m (10,500 and 12,500 ft) of elevation. A small body of permafrost, less than 25 m (80 ft) across, was found at the summit of Mauna Kea before 1974, and may still be present. Small gullies etch the summit, formed by rain- and snow-fed streams that flow only during winter melt and rain showers.
Question: What was likely covered by later lava flows on Mauna Loa?
glaciation.
