Input: Madonna (entertainer)
Her mature artistic statement was visible in True Blue (1986) and Like a Prayer (1989). In True Blue, she incorporated classical music in order to engage an older audience who had been skeptical of her music. Like a Prayer introduced live recorded songs and incorporated different genres of music, including dance, funk, R&B and gospel music. Her versatility was further shown on I'm Breathless, which consists predominantly of the 1940s Broadway showtune-flavoured jazz, swing and big band tracks. Madonna continued to compose ballads and uptempo dance songs for Erotica (1992) and Bedtime Stories (1994). Both albums explored element of new jack swing, with Jim Farber from Entertainment Weekly saying that "she could actually be viewed as new jack swing's godmother." She tried to remain contemporary by incorporating samples, drum loops and hip hop into her music. With Ray of Light, Madonna brought electronic music from its underground status into massive popularity in mainstream music scene.

Input: Aircraft carrier
Although STOVL aircraft are capable of taking off vertically from a spot on the deck, using the ramp and a running start is far more fuel efficient and permits a heavier launch weight. As catapults are unnecessary, carriers with this arrangement reduce weight, complexity, and space needed for complex steam or electromagnetic launching equipment, vertical landing aircraft also remove the need for arresting cables and related hardware. Russian, Chinese, and future Indian carriers include a ski-jump ramp for launching lightly loaded conventional fighter aircraft but recover using traditional carrier arresting cables and a tailhook on their aircraft.

What do Russian carriers include for launching lightly loaded conventional fighters?
Output: a ski-jump ramp
