29. Although the majority of low-speed engines and many medium-speed engines are
operated on heavy fuels, there is still a balance to be struck between the lower cost of the heavier
fuels and the inconvenience and greater cost of fuel treatment and increased engine maintenance
that inevitably results from their use. Therefore,
(A) the use of heavy fuels could increase the cost of fuel treatment.
(B) the use of heavy fuels could reduce the maintenance duty.
(C) the inconvenience of fuel treatment is induced by the increased engine maintenance.
(D) the use of heavy fuels is not appropriate for low-speed engine but is acceptable for mediumspeed engine.

雖然大多數低速引擎和許多中速引擎都使用重油（Heavy Fuels）運轉，但仍必須在「重油較低的採購成本」與「因使用重油而不可避免帶來的燃油處理不便、高昂的處理成本，以及增加的引擎維護費用」之間取得平衡。因此：
(A) 使用重油可能會增加燃油處理的成本。
(B) 使用重油可以減少維護工作。
(C) 燃油處理的不便，是由增加的引擎維護所引起的。
(D) 使用重油不適用於低速引擎，但對中速引擎是可接受的。
