Problem: Please answer a question about the following article about Hellenistic period:
Hellenistic Geometers such as Archimedes (c.287 212 BC), Apollonius of Perga (c.262 c.190 BC), and Euclid (c.325 265 BC), whose Elements became the most important textbook in mathematics until the 19th century, built upon the work of the Hellenic era Pythagoreans. Euclid developed proofs for the Pythagorean Theorem, for the infinitude of primes, and worked on the five Platonic solids. Eratosthenes used his knowledge of geometry to measure the circumference of the Earth. His calculation was remarkably accurate. He was also the first to calculate the tilt of the Earth's axis (again with remarkable accuracy). Additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day. Known as the "Father of Geography ", Eratosthenes also created the first map of the world incorporating parallels and meridians, based on the available geographical knowledge of the era.
Who worked on the five Platonic solids?
A: Euclid
Problem: Please answer a question about the following article about Financial crisis of 2007%E2%80%9308:
Prior to the crisis, financial institutions became highly leveraged, increasing their appetite for risky investments and reducing their resilience in case of losses. Much of this leverage was achieved using complex financial instruments such as off-balance sheet securitization and derivatives, which made it difficult for creditors and regulators to monitor and try to reduce financial institution risk levels. These instruments also made it virtually impossible to reorganize financial institutions in bankruptcy, and contributed to the need for government bailouts.
Who bailed out financial institutions?
A: government
