Read the passage.In many ways, life in the 1800s was much more difficult than it is today. Travel, for instance, was much slower. Instead of quick-moving airplanes, people traveled by horse, coach, and also by train. Just like slow travel, limited long-distance communication also added to the hardships of the people.

The sentence compares limited long-distance communication with slow travel: both made life harder in the 1800s. “As with” expresses that comparison and fits the sentence: “As with slow travel, limited long-distance communication also added to the hardships of the people.” “However” and “in contrast” suggest opposition, while “although” needs a different sentence structure.
