In the last years of the 19th century the term "Near East" acquired considerable disrepute in eyes of the English-speaking public as did the Ottoman Empire itself. The cause of the onus was the Hamidian Massacres of Armenians because they were Christians, but it seemed to spill over into the protracted conflicts of the Balkans. For a time, "Near East" meant primarily the Balkans. Robert Hichens' book The Near East (1913) is subtitled Dalmatia, Greece and Constantinople.

When did the term "Near East" acquire considerable disrepute?
Answer: the 19th century

Resistance to infection (immunity) may be acquired following a disease, by asymptomatic carriage of the pathogen, by harboring an organism with a similar structure (crossreacting), or by vaccination. Knowledge of the protective antigens and specific acquired host immune factors is more complete for primary pathogens than for opportunistic pathogens. There is also the phenomenon of herd immunity which offers a measure of protection to those otherwise vulnerable people when a large enough proportion of the population has acquired immunity from certain infections.

When may immunity be acquired?
Answer: following a disease

The world's largest deposit of natural bitumen, known as the Athabasca oil sands is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous, and is composed of numerous lenses of oil-bearing sand with up to 20% oil. Isotopic studies attribute the oil deposits to be about 110 million years old. Two smaller but still very large formations occur in the Peace River oil sands and the Cold Lake oil sands, to the west and southeast of the Athabasca oil sands, respectively. Of the Alberta bitumen deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining. The other 80% has to be produced by oil wells using enhanced oil recovery techniques like steam-assisted gravity drainage.

What formative period produced bitumen?
Answer:
early Cretaceous
