In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: Does Amtrak go into Canada? Passage:Everett Station is served by six daily Amtrak trains: four Cascades runs between Seattle and Vancouver, British Columbia, and two Empire Builder runs between Seattle and Chicago. The station is also served by the North Line of Sound Transit's Sounder commuter rail service, running four trains in peak direction towards King Street Station in Seattle during the morning commute and four trains from Seattle during the evening commute, only on weekdays and during special events. Train service to Everett is most often disrupted and canceled during the autumn and winter seasons because of landslides along the shoreline of the Puget Sound, where the BNSF mainline tracks run. During the 20122013 winter season, a record-high of 206 passenger trains between Everett and Seattle were canceled, prompting the Washington State Department of Transportation to begin a three-year landslide mitigation project in 2013 that will stabilize slopes above the railroad between Seattle and Everett.
