Two groups of invertebrates have notably complex brains: arthropods (insects, crustaceans, arachnids, and others), and cephalopods (octopuses, squids, and similar molluscs). The brains of arthropods and cephalopods arise from twin parallel nerve cords that extend through the body of the animal. Arthropods have a central brain with three divisions and large optical lobes behind each eye for visual processing. Cephalopods such as the octopus and squid have the largest brains of any invertebrates.

Which two groups of invertebrates have complex brains?
Answer: arthropods (insects, crustaceans, arachnids, and others), and cephalopods

The Pala Empire (Bengali: পাল সাম্রাজ্য Pal Samrajyô) flourished during the Classical period of India, and may be dated during 750–1174 CE. Founded by Gopala I, it was ruled by a Buddhist dynasty from Bengal in the eastern region of the Indian subcontinent. Though the Palas were followers of the Mahayana and Tantric schools of Buddhism, they also patronised Shaivism and Vaishnavism. The morpheme Pala, meaning "protector", was used as an ending for the names of all the Pala monarchs. The empire reached its peak under Dharmapala and Devapala. Dharmapala is believed to have conquered Kanauj and extended his sway up to the farthest limits of India in the northwest. The Pala Empire can be considered as the golden era of Bengal in many ways. Dharmapala founded the Vikramashila and revived Nalanda, considered one of the first great universities in recorded history. Nalanda reached its height under the patronage of the Pala Empire. The Palas also built many viharas. They maintained close cultural and commercial ties with countries of Southeast Asia and Tibet. Sea trade added greatly to the prosperity of the Pala kingdom. The Arab merchant Suleiman notes the enormity of the Pala army in his memoirs.

What style of belief system did the Pala Empire favor?
Answer: Buddhist

Energy production in Greece is dominated by the Public Power Corporation (known mostly by its acronym ΔΕΗ, or in English DEI). In 2009 DEI supplied for 85.6% of all energy demand in Greece, while the number fell to 77.3% in 2010. Almost half (48%) of DEI's power output is generated using lignite, a drop from the 51.6% in 2009. Another 12% comes from Hydroelectric power plants and another 20% from natural gas. Between 2009 and 2010, independent companies' energy production increased by 56%, from 2,709 Gigawatt hour in 2009 to 4,232 GWh in 2010.

What percentage did independent companies' energy production increase between 2009 and 2010?
Answer:
56%
