Question

Which sentences in this excerpt highlight information that the author uses to show that the disease spreads in a different manner than was assumed at the time?
1.. This assumption led to very conflicting opinions respecting the disease.

2.A little reflection shows, however, that we have no right thus to limit the way in which a disease may be propagated, for the communicable diseases of which we have a correct knowledge spread in very different manners.

3.A consideration of the pathology of cholera is capable of indicating to us the manner in which the disease is communicated.

4. But from all that I have been able to learn of cholera, both from my own observations and the descriptions of others, I conclude that cholera invariably commences with the affection of the alimentary canal.

5.The disease often proceeds with so little feeling of general illness, that the patient does not consider himself in danger, or even apply for advice, till the malady is far advanced.
