Attached is the picture of the graduated cylinder.

You have to take into account two things to reply the question:

1) The lecture is given by the meniscus, which leads you to read 69.

2)  The number of significative figures: the last significant figure reported is uncertain, so the number is reported as 69.0, that means that the reading is 69 plus or minus an error.

Answer: 69.0 mL
