How to use 'pose'?

[Maggie]

Hi, guys

Autonomic Computing is an initiative started by IBM in 2001. Its ultimate aim is to create computer systems capable of self-management, to overcome the rapidly growing complexity of computing systems management, and to reduce the barrier that that complexity poses to further growth.

1. I think that complexity is a subject and pose is a verb. The first 'that' (reduce the barrier that that complexity poses to further growth)replaces 'the barrier'? Am I right?

2. How to use this kind of sentence correctly, such as 'poses to further growth'?

For instance,these couples of years laterly, the economy depression poses many problems for our societies throughout all over the world.

I made a sentence to pratice how to use 'pose'. Could you check it out if I use it correctly? And would you mind making a sentence for me as well? Here I didn't find out an example to use 'pose to' actually. I mean how to use 'pose' and use a preposition 'to' together in a sentence.

Thanks so much Maggie^^

Hi Maggie,

Let me give some examples: If you pose a scenario/a problem. what you are doing is offering/putting forward something for consideration as in: When you asked that question, you posed an interesting point.

You can also 'pose' in the sense that you stand/hold yourself in a particular way often to have your photograph taken as in: The photographer asked the model to pose with a look in her eyes as though she was looking out to sea.

The again 'pose' can be a noun as in the way you stand/an attitude of mind.

Hi Alan,

Thanks for your reacting.

And would you minding telling me that what's the meaning of 'and to reduce the barrier that that complexity poses to further growth'?

I think pose in this sentence means 'cause'. Am I right?

Thanks a million.

Hi,

'and to reduce the barrier that that complexity poses to further growth'? = and to make less difficult whatever stands in the way of growth in the future.
