Which clause in the passage is written in the passive voice? adapted from Is There Life On Mars?
by Dr. Marc Fries
This is an idea that many people have pondered and speculated about for hundreds of years, and it is one that I have wondered about for most of my own life.
Earth is the only place that we know of where there is life. Many people have studied Mars, and some have even said that they thought they saw signs of life. We now know they were fooled by what they were able to see because they did not have telescopes that were powerful enough. To really confirm the existence of life on Mars, we need a close-up look at the planet!
Robotic spacecraft have given us great views of the planet, providing us with more information about the planet than we ever thought possible. Still, no humans have ever tried to go to Mars, and no human missions to Mars will be tried for years. In fact, the first people on Mars may be your age today. When you are grown, maybe you will watch—or even be one of—the people who make the first trip to Mars

workshop on enhancing communication around influenza vaccination (weeciv)

context

investment in early intervention health care is a proven strategy to decrease high costs burdening the public and government sectors. by strengthening preparedness capacity and supporting low-cost preventative services, mortality rates and the health of populations can be significantly improved. over the past 6 years, considerable investments have been made to establish and expand influenza vaccine manufacturing capacity in developing countries. these investments have improved preparedness for seasonal and pandemic influenza, and have indirectly improved health systems, surveillance, detection, and response activities by leveraging additional support and building capacity within these countries and regions. to fully maximize investments and to ensure sustainability of influenza vaccine manufacturing in developing countries, there is a need to increase national and regional uptake of vaccination.

the percentage of who member states incorporating seasonal influenza vaccination into national immunization programs remains low with significant regional variations. high vaccine and service costs, competing health priorities, difficulties in measuring vaccine efficacy and cost–effectiveness, and adverse public opinion regarding vaccination all influence the policy decisions affecting national immunization programs.

effectively communicating the benefit of influenza vaccination is an essential component to increase the vaccine uptake and inclusion into national influenza immunization programmes. firstly, these benefits need to be understood by the key players that promote vaccination at national level (health promotion departments and healthcare workers). health care workers are increasingly important in influencing vaccination choices, and new appro
