How are doubles falling between 61–99 (66, 77, 88, and 99) produced? (3 points) Responses with a reverse fingerspelling direction with a reverse fingerspelling direction with a standard fingerspelling direction and palm orientation with a standard fingerspelling direction and palm orientation with a standard fingerspelling direction, but downward palm orientation with a standard fingerspelling direction, but downward palm orientation with a standard fingerspelling direction, but upward palm orientation

Doubles falling between 61–99 (66, 77, 88, and 99) are produced using a standard fingerspelling direction and palm orientation. The signer would hold their hand in front of their body in a neutral position with their palm facing towards the signer. Then, they would produce the corresponding double digits using the standard fingerspelling alphabet.

For example, to sign "66", the signer would extend their index finger and middle finger together, representing the number 6, and then repeat the same handshape to represent the second 6.

The same process would be applied for "77" (representing the number 7 twice), "88" (representing the number 8 twice), and "99" (representing the number 9 twice).

It's important to note that the palm orientation remains the same throughout, with the palm facing towards the signer. Additionally, the direction of the fingerspelling is standard, moving from left to right (assuming the signer is right-handed). The palm would not be facing downward or upward for these signs.
