The four sentences (labelled 1, 2, 3, 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer:1. In the central nervous systems of other animal species, such a comprehensive regeneration of neurons has not yet been proven beyond doubt.2. Biologists from the University of Bayreuth have discovered a uniquely rapid form of regeneration in injured neurons and their function in the central nervous system of zebrafish.3. They studied the Mauthner cells, which are solely responsible for the escape behaviour of the fish, and previously regarded as incapable of regeneration.4. However, their ability to regenerate crucially depends on the location of the injury.

M2 Question 9 Text 1 Most animals can regenerate some parts of their bodies, such as skin. But when a three-banded panther worm is cut into three pieces, each piece grows into a new worm. Researchers are investigating this feat partly to learn more about humans’ comparatively limited abilities to regenerate, and they’re making exciting progress. An especially promising discovery is that both humans and panther worms have a gene for early growth response (EGR) linked to regeneration. Text 2 When Mansi Srivastava and her team reported that panther worms, like humans, possess a gene for EGR, it caused excitement. However, as the team pointed out, the gene likely functions very differently in humans than it does in panther worms. Srivastava has likened EGR to a switch that activates other genes involved in regeneration in panther worms, but how this switch operates in humans remains unclear.9 Mark For ReviewBased on the texts, what would the author of Text 2 most likely say about Text 1’s characterization of the discovery involving EGR? A) It is reasonable given that Srivastava and her team have identified how EGR functions in both humans and panther worms. B) It is overly optimistic given additional observations from Srivastava and her team. C) It is unexpected given that Srivastava and her team’s findings were generally met with enthusiasm. D) It is unfairly dismissive given the progress that Srivastava and her team have reported.
