Directions: Given below is a paragraph that has blank spaces. Corresponding to each
blank, five options are given, out of which only one is appropriate. Choose the option that fits most
suitably in the given blank making sentence grammatically and contextually correct.

Gaseous refinery **__________________(I)** include hydrogen, fuel gas, ethane, propane, and butane. Most of the hydrogen is **__________________(II)** in refinery desulfurization facilities, which remove hydrogen sulfide from the gas stream and then separate that compound into elemental hydrogen and sulfur; small quantities of the hydrogen may be delivered to the refinery fuel system. Refinery fuel gas varies in composition but usually contains a **__________________(III)** amount of methane; it has a heating value similar to natural gas and is consumed in plant operations. The drawback is that periodic variability in heating value makes it **__________________(IV)** for delivery to consumer gas systems. Ethane may be **__________________(V)** from the refinery fuel system for use as a petrochemical feedstock. In many cases, these operations take place in relatively remote regions and affect only those employed by the industry, so that little or no **__________________(VI)** is attempted.

In many cases, these operations take place in relatively remote regions and affect only those employed by the industry, so that little or no **__________________(VI)** is attempted.

Accepted Answer

**Solution:**

1. The sentence containing the blank (24) states: "The drawback is that periodic variability in heating value makes it __________________(24) for delivery to consumer gas systems."

2. The word "drawback" indicates a negative aspect, so the blank should be filled with a word that conveys a negative or unfavorable condition.

3. Among the options:
   - (a) *unsuitable* means not appropriate or not fit for a purpose, which fits the context of a drawback.
   - (b) *acceptable* means satisfactory or adequate, which contradicts the idea of a drawback.
   - (c) *satisfying* means fulfilling expectations, also contradicting the drawback.
   - (d) *appropriate* means suitable or proper, again contradicting the drawback.
   - (e) *improperly* is an adverb and does not fit grammatically in the blank which requires an adjective.

4. Therefore, the correct choice is **(a) unsuitable**.

**Answer:** (a) unsuitable
