Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Passage: Phycobilins are a third group of pigments found in cyanobacteria, and glaucophyte, red algal, and cryptophyte chloroplasts. Phycobilins come in all colors, though phycoerytherin is one of the pigments that makes many red algae red. Phycobilins often organize into relatively large protein complexes about 40 nanometers across called phycobilisomes. Like photosystem I and ATP synthase, phycobilisomes jut into the stroma, preventing thylakoid stacking in red algal chloroplasts. Cryptophyte chloroplasts and some cyanobacteria don't have their phycobilin pigments organized into phycobilisomes, and keep them in their thylakoid space instead. Question: What color is phycoerytherin?
red

Passage: Endospores show no detectable metabolism and can survive extreme physical and chemical stresses, such as high levels of UV light, gamma radiation, detergents, disinfectants, heat, freezing, pressure, and desiccation. In this dormant state, these organisms may remain viable for millions of years, and endospores even allow bacteria to survive exposure to the vacuum and radiation in space. According to scientist Dr. Steinn Sigurdsson, "There are viable bacterial spores that have been found that are 40 million years old on Earth — and we know they're very hardened to radiation." Endospore-forming bacteria can also cause disease: for example, anthrax can be contracted by the inhalation of Bacillus anthracis endospores, and contamination of deep puncture wounds with Clostridium tetani endospores causes tetanus. Question: How long can endospores of bacteria stay alive in dormant state?
for millions of years

Passage: Under the 1830 Act any householder who paid rates could apply, with a one-off payment of two guineas (roughly equal in value to £168 today), to sell beer or cider in his home (usually the front parlour) and even to brew his own on his premises. The permission did not extend to the sale of spirits and fortified wines, and any beer house discovered selling those items was closed down and the owner heavily fined. Beer houses were not permitted to open on Sundays. The beer was usually served in jugs or dispensed directly from tapped wooden barrels on a table in the corner of the room. Often profits were so high the owners were able to buy the house next door to live in, turning every room in their former home into bars and lounges for customers. Question: What did the Beer Act allow a householder to sell from his home?

beer or cider
