Question: Read this and answer the question

Some polychaetes breed only once in their lives, while others breed almost continuously or through several breeding seasons. While most polychaetes remain of one sex all their lives, a significant percentage of species are full hermaphrodites or change sex during their lives. Most polychaetes whose reproduction has been studied lack permanent gonads, and it is uncertain how they produce ova and sperm. In a few species the rear of the body splits off and becomes a separate individual that lives just long enough to swim to a suitable environment, usually near the surface, and spawn.

How do some annelids get a one-time chance at a better spawning spot?
Answer: the rear of the body splits off and becomes a separate individual

Problem: Darwin had initially decided to call his book An abstract of an Essay on the Origin of Species and Varieties Through natural selection, but with Murray's persuasion it was eventually changed to the snappier title: On the Origin of Species, with the title page adding by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. Here the term "races" is used as an alternative for "varieties" and does not carry the modern connotation of human racesthe first use in the book refers to "the several races, for instance, of the cabbage" and proceeds to a discussion of "the hereditary varieties or races of our domestic animals and plants".
What title did Darwin's book ultimately have?
The answer is the following: On the Origin of Species

TB infection begins when the mycobacteria reach the pulmonary alveoli, where they invade and replicate within endosomes of alveolar macrophages. Macrophages identify the bacterium as foreign and attempt to eliminate it by phagocytosis. During this process, the bacterium is enveloped by the macrophage and stored temporarily in a membrane-bound vesicle called a phagosome. The phagosome then combines with a lysosome to create a phagolysosome. In the phagolysosome, the cell attempts to use reactive oxygen species and acid to kill the bacterium. However, M. tuberculosis has a thick, waxy mycolic acid capsule that protects it from these toxic substances. M. tuberculosis is able to reproduce inside the macrophage and will eventually kill the immune cell.
What vesicle is the temporary holding room for the M. tuberculosis bacterium during phagocytosis?
phagosome

On 6 February 2015, it was announced that Judge Richard Marks is to be replaced by Judge Charles Wide at the retrial. Two days earlier, Marks had emailed counsel for the defendants telling them: "It has been decided (not by me but by my elders and betters) that I am not going to be doing the retrial". Reporting the decision in UK newspaper The Guardian, Lisa O'Carroll wrote: "Wide is the only judge so far to have presided in a case which has seen a conviction of a journalist in relation to allegations of unlawful payments to public officials for stories. The journalist, who cannot be named for legal reasons, is appealing the verdict". Defence counsel for the four journalists threatened to take the decision to judicial review, with the barrister representing Pharo, Nigel Rumfitt QC, saying: "The way this has come about gives rise to the impression that something has been going on behind the scenes which should not have been going on behind the scenes and which should have been dealt with transparently". He added that the defendants were "extremely concerned" and "entitled" to know why Marks was being replaced by Wide.

In which newspaper did Lisa O'Carroll report the choice of judge?
Output: The Guardian

Input: Article: The Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty (c. 1050256 BC). The coinage issued by the central government mint in 119 BC remained the standard coinage of China until the Tang dynasty (618907 AD). The period saw a number of limited institutional innovations. To pay for its military campaigns and the settlement of newly conquered frontier territories, the government nationalized the private salt and iron industries in 117 BC, but these government monopolies were repealed during the Eastern Han period. Science and technology during the Han period saw significant advances, including papermaking, the nautical steering rudder, the use of negative numbers in mathematics, the raised-relief map, the hydraulic-powered armillary sphere for astronomy, and a seismometer employing an inverted pendulum.

Now answer this question: A seismometer during the Han dynasty used what type of pendulum?

Output: inverted
