I'm trying to write a motivation letter and I'm having doubts when writing a couple of sentences using ing termination or not.
- To enroll in this course will allow me to pursue my career goal of considerably improve and update my skills (vs considerably improving and updating my skills)
- I worked remotely as a free-lancer for a company which challenged me to transmit data through ultrasound in air (vs challenged me to transmitting data through ultrasound in air )
More interested than in knowing which option is correct, I'm interested in understanding why. Just for the record I'm a Spanish speaking native
