1 : Thick glass may P : which are available Q : of the home bottle-cuttlers R : in many large stores, but any fine S : be cut with one 6 : glass requires personal attention. The Proper sequence should be:

The correct answer is: A. PSQR

Here is a brief explanation of each option:

• PSQR: This is the correct sequence. Thick glass may be cut with one of the home bottle-cuttlers, which are available in many large stores, but any fine glass requires personal attention.
• QPSR: This option is incorrect because it puts the phrase “which are available in many large stores” after the phrase “but any fine glass requires personal attention.” This makes it sound like the availability of home bottle-cuttlers is dependent on the need for personal attention when cutting fine glass.
• RQSP: This option is incorrect because it puts the phrase “but any fine glass requires personal attention” at the beginning of the sentence. This makes it sound like the need for personal attention when cutting fine glass is the most important thing to know about cutting glass.
• SQPR: This option is incorrect because it puts the phrase “one of the home bottle-cuttlers” after the phrase “but any fine glass requires personal attention.” This makes it sound like there is only one home bottle-cutter that can be used to cut fine glass.

I hope this explanation is helpful!
