The new book has beautiful … which make it attractive.

Step 1: Analyze the question The sentence is: "The new book has beautiful ___ which make it attractive." We need a noun that describes something in a book that makes it look appealing.

Step 2: Explain the concept (vocabulary in context) Look at the meaning of each option:

• Illustrations: pictures, drawings, or diagrams in a book. This fits perfectly.
• Demonstrations: practical shows of how something works, or public protests. These are not found in a book.
• Illuminations: decorative lighting, or hand-painted decorations in old manuscripts. The word is rare and does not suit a "new book" in everyday usage.
• Compositions: written works, essays, or pieces of music. They are not "beautiful features that make a book attractive" in this sense.

Step 3: Solution A new book becomes attractive when it has beautiful pictures and drawings. The word for these is illustrations.

Test it: "The new book has beautiful illustrations which make it attractive." The sentence reads naturally and the meaning is clear.

Step 4: Answer The correct option is A. illustrations.

Tip: Be careful with look-alike words such as illustration and illumination. Remember: illustrate = show with pictures, while illuminate = light up. In exams, always read the whole sentence and ask, "What would a book have that makes it attractive?" The answer is pictures, so the word is illustrations.
