वाक्य के उस भाग को पहचानें जिसमें व्याकरण संबंधी त्रुटि है, यदि कोई त्रुटि नहीं है तो "No Error" अंकित करें।

Alex always travels (a) /  by air and stays in five-stars (b) / hotels as he is rich and can afford it. (c) / No error (d) 

The correct answer is option 2) i.e. b.

Key Points

• In the part, 'b' of the given sentence 'five-stars' has been used which is wrong.
• Hyphenated nouns do not have a plural form, hence, 'five-star' will be used.
  Example: He gave me two-hundred-rupees notes. (wrong)
                   He gave me two-hundred-rupee notes. (right)

Additional Information

• A compound noun is a noun that is made with two or more words. A compound noun is usually [noun + noun] or [adjective + noun], but there are other combinations (see below). Each compound noun acts as a single unit and can be modified by adjectives and other nouns.

  • There are three forms for compound nouns:

    • open or spaced - space between words (tennis shoe)
    • hyphenated - hyphen between words (six-pack)
    • closed or solid - no space or hyphen between words (bedroom)
• Alexa is singular, so the singular verb 'travels' is right to use.

So, the correct sentence will be: Alex always travels by air and stays in five-star hotels, as he is rich and can afford it.
