Let’s go step by step to answer the five questions based on the snake venom data.

---

Step 1: Read and list all the snakes with their mortality rates

From the text:

- Southern United States copperhead → less than 1% (we’ll treat this as <1%, so very low)
- Western diamondback rattlesnake → 5–15%
- Eastern coral snake → 5–20%
- King cobra → greater than 40% (>40%)
- Indian krait → 77%
- European viper → 1–5%
- Bushmaster → usually 100%
- Fer-de-lance → 10–20%
- Black-necked cobra → 11–40%
- Puff adder → 11–40%

Total snakes observed: Let’s count — that’s 10 snakes. ✔️

Question 1: Which snake venom has the highest mortality rate?

Look for the highest number or range.

- Bushmaster = “usually 100%” → that’s the highest possible.
- Indian krait = 77% → high, but not as high as 100%.
- King cobra = >40% → could be 41% to 99%, still less than 100%.

✔ So, bushmaster has the highest mortality rate.

---

Question 2: Which snake venom has the lowest mortality rate?

Look for the smallest number or range.

- Southern US copperhead = “less than 1%” → this is lower than any other listed (even European viper starts at 1%).
- European viper = 1–5% → minimum is 1%, which is higher than “less than 1%”.

✔ So, southern United States copperhead has the lowest mortality rate.

---

Question 3: Which two snakes have the same mortality percentage?

Look for overlapping ranges or identical numbers.

- Black-necked cobra: 11–40%
- Puff adder: 11–40%

These two have the exact same range.

Also, western diamondback rattlesnake (5–15%) and eastern coral snake (5–20%) overlap, but they’re not the same.

Fer-de-lance (10–20%) overlaps with others too, but again, not identical.

Only black-necked cobra and puff adder have the *exact same* range: 11–40%.

✔ So, black-necked cobra and puff adder have the same mortality percentage.

Question 4: How many snakes were observed?

The text says: “scientists collected the venom of ten snakes.”

Then it lists them:

1. Southern US copperhead
2. Western diamondback rattlesnake
3. Eastern coral snake
4. King cobra
5. Indian krait
6. European viper
7. Bushmaster
8. Fer-de-lance
9. Black-necked cobra
10. Puff adder

That’s 10.

✔ Answer: 10

Question 5: From the information recorded can you determine the snake whose venom works the most rapidly? The least rapidly? Explain.

Important: The data given is about mortality percent, not speed of venom effect.

Mortality rate tells us how often the venom kills, not how fast it kills.

For example, bushmaster kills 100% of victims — but we don’t know if it takes 1 hour or 1 day.

Indian krait kills 77% — maybe very fast, maybe slow.

No information is given about time to death or speed of action.

✔ So, no, we cannot determine which venom works most or least rapidly — because the data only shows mortality percentage, not speed.

Final Answers:

1. Bushmaster
2. Southern United States copperhead
3. Black-necked cobra and puff adder
4. 10
5. No — the data only shows mortality percentage, not how quickly the venom acts.
