Q.For each of the following statements, determine whether an inclusive “Or” or exclusive “Or” is used. Give reasons for your answer.

The "or" in a statement is inclusive when both possibilities can occur simultaneously, and exclusive when at most one of the possibilities can occur.

1. "To enter a country, you need a passport or a voter registration card." A traveller may possess both documents — having both does not disqualify entry. So this Or is inclusive.
2. "The school is closed if it is a holiday or a Sunday." A Sunday is itself often already a holiday, so both conditions can hold together on the same day without contradiction. So this Or is inclusive.
3. "Two lines intersect at a point or are parallel." Two distinct lines in a plane cannot both intersect at a point and be parallel at the same time — these are mutually exclusive geometric possibilities. So this Or is exclusive.
4. "Students can take French or Sanskrit as their third language." A student is normally permitted to choose exactly one third language, not both simultaneously. So this Or is exclusive.
   ✓Final answer

   (i) Inclusive (ii) Inclusive (iii) Exclusive (iv) Exclusive.

Ask: can both alternatives be true for the same subject at the same time without contradiction? If yes, the Or is inclusive; if the alternatives are mutually incompatible, the Or is exclusive.

• Assuming every everyday "or" is automatically exclusive — many real-life "or"s (like document requirements) are inclusive.
• Not checking whether the two options can logically coexist (e.g., missing that a Sunday can be a holiday too).
