1. Is argument “initial_value” required in =REDUCE?

A. No
B. —
C. No ✓
D. Yes

Explanation: “initial_value” is optional.

2. In =REDUCE, which is argument #1?

A. lambda
B. value
C. initial_value ✓
D. range

Explanation: Argument #1 is “initial_value”.

3. Which formula is a valid example of =REDUCE?

A. =LAMBDA(, A1:C2, LAMBDA(a,b,a+b^2))
B. =REDUCE(, A1:C2, LAMBDA(a,b,a+b^2)) ✓
C. =REDUCE(, A1:C2, LAMBDA(a,b,a+b^2), 0)
D. REDUCE(, A1:C2, LAMBDA(a,b,a+b^2))

Explanation: Correct example: =REDUCE(, A1:C2, LAMBDA(a,b,a+b^2))

4. Is argument “array” required in =REDUCE?

A. —
B. No
C. Yes

6. Does =REDUCE return a dynamic array?

A. No ✓
B. No
C. Yes
D. —

Explanation: REDUCE does not spill.

7. What usually causes #VALUE! in =REDUCE?

A. Volatile and recalculates every time
B. Providing an invalid LAMBDA function or an incorrect number of parameters returns a #VALUE! error called "Incorrect Parameters". ✓
C. Text is always ignored
D. Select entire column for best performance

Explanation: Providing an invalid LAMBDA function or an incorrect number of parameters returns a #VALUE! error called "Incorrect Parameters". — Fix: Check the number of LAMBDA parameters

8. What is the fix for #VALUE! in =REDUCE?

A. Check the number of LAMBDA parameters ✓
B. Requires add-in
C. Select entire column for best performance
D. Volatile and recalculates every time

Explanation: Providing an invalid LAMBDA function or an incorrect number of parameters returns a #VALUE! error called "Incorrect Parameters". — Fix: Check the number of LAMBDA parameters
