Final answer:
Among the sentences, option D, 'London was in there for another dense fog within the next four and 20 hours', offers an example of foreshadowing, while option E, 'Do you remember, he said, the day in the winter of 1898, the day that the petroleum ship exploded?' constitutes a flashback. Both reveal Martin Hackness's instincts about adverse weather conditions and the importance of advance warning.
Step-by-step explanation:
The question asks for two sentences that either foreshadow or indicate a flashback in terms of Martin Hackness's instincts concerning weather-related issues. Foreshadowing indicates an event that might happen later in the story, while a flashback refers to an event that happened in the past. Based on this, option D, '
London was in there for another dense fog within the next four and 20 hours
', is an example of foreshadowing because it presents a prediction of coming weather-related trouble. For the flashback, option E, '
Do you remember, he said, the day in the winter of 1898, the day that the petroleum ship exploded?
' is a suitable choice as it refers back to a past event. Both sentences exhibit Martin Hackness's attention towards the weather, conveying his concerns and the need for advance warning.
