For a certain province, the table shows all of the types of places in the province where removal of various types of invertebrates from tide pools requires a permit. An "x" indicates that a permit is required to take the invertebrate from tide pools in the specified type of place. A blank space indicates that no permit is required. Types of invertebrates not listed in the table may be removed without a permit from any tide pool in the province.
| Invertebrates | Marine life refuges | Provincial parks | National parks | All other parks |
|---|
| Abalones | x | [ ] | x | [ ] |
| Ghost shrimp | x | [ ] | [ ] | x |
| Limpets | [ ] | x | x | [ ] |
| Mussels | [ ] | x | [ ] | [ ] |
| Octopuses | x | x | [ ] | x |
| Sea urchins | x | [ ] | x | x |
For each of the following statements about permit requirements in the province, select
Correct if the information provided indicates that the statement is correct. Otherwise, select
Incorrect.
The info we can gather from the question stem is that x means a permit is required, while a blank space or [ ] means no permission required.
1. A permit is required for removal of sea urchins from tide pools everywhere a permit is required for removal of abalones from tide pools.
Solution: So, in whichever column abalones have a 'x', the sea urchins should also have a 'x'.
Don't take it as oppositeAbalones have a 'x' in 1st and 3rd column(marine life refuge and national park), and so does sea urchin (It does not matter if sea urchins has 'x' in more columns than these two specified.)Correct2. Mussels may be removed from tide pools without a permit anywhere octopuses may be removed from tide pools without a permit.
Solution: So, in whichever column octopuses have a '[ ]', the Mussels should also have a '[ ]'.
Don't take it as opposite again.Octopuses have a '[ ]' in 3rd column(National parks), and so does Mussels (It does not matter if Mussels has '[ ]' in more columns than the required 3rd column.)Correct3. If a type of invertebrate may be removed from tide pools without a permit in a marine life refuge, it may also be removed from tide pools without a permit anywhere outside a provincial or national park.
Solution: So, in whichever row marine life refuge has a '[ ]', all other parks should also have a '[ ]'.
outside provincial or national park would mean all other parks.marine life refuge have a '[ ]' in 3rd and 4th rows(Limpets and Mussels), and so does all other parks (It does not matter if all other parks has '[ ]' in more rows than the required 3rd and 4th row.)Correct
